Tesla Model S owner reminds us of ‘Active Hood’ pedestrian safety feature

Published

on

A relatively unknown Tesla safety feature called ‘Active Hood’, designed to reduce head injuries to pedestrians in the event of a frontal collision, was brought to light in a recent Model S owner’s video that attempts to capture Tesla’s Automatic Emergency Braking (AEB) in action. Active Hood which exists on European and Australian Model S vehicles uses pyrotechnics to raise the rear of the hood by several inches in order to soften the impact of a pedestrian and cyclist against a windshield during frontal impact.

Model S owner and Tesla Motors Club forum member Carspotter Daily posted a video that attempts to simulate a vehicle-pedestrian interaction. The vehicle was a first generation Autopilot vehicle under Firmware 8.0. It’s unclear whether CarSpotter was intentionally trying to trigger Tesla’s Active Hood feature or whether they were looking to test the AEB system, but despite not being able to trigger either feature the end result revealed, once again, Autopilot’s ability to detect humans. Another Tesla owner YouTuber KmanAuto first detected the pedestrian alert last November when he put a friend in front of of his moving Model S.

This type of granular detection of objects allows the vehicle to respond to potential collisions in the most appropriate way, with the objective to reduce collisions entirely. Though Active Hood was mentioned in the trailing notes at the end of the recent video, it’s not clear if the vehicle used in the video is a U.S. spec Model S or a European/Australian version that was included with that safety feature.

Active Hood is not a new feature but the fact that it has only been implemented on Tesla vehicles in select markets that mandate the technology has kept it largely under the radar. The technology was built into Tesla vehicles to comply with Euro NCAP Pedestrian Safety requirements that mandate vehicle manufacturers to maintain clearances between the hood and structural components underneath, to protect pedestrians in the event of a low to medium speed collision. These accidents often prove fatal to the pedestrian, as collisions at low to medium speeds typically cause the pedestrian’s body to fold over the hood with the head hitting the windshield.

The system was put to use in real world conditions in Australia in 2015 when someone driving a Tesla Model S collided with a kangaroo which caused the system to deploy. From what they saw after the accident, it looked like the adolescent ‘roo had a broken leg but was conscious enough after the accident to limp away which seems to indicate that it was successful in preventing immediate head trauma.

Tesla had a special challenge when designing Active Hood since the front trunk of a Model S is sealed to keep water out whereas hoods to internal combustion engine vehicles  are generally vented. US Patent Application US20130076076 A1 details the specific challenges and solutions developed to allow the hood to pop up in response to an imminent collision with a pedestrian.

The English European version of the Tesla Model S manual lays out the technology in a much more user friendly format:

Active Hood

Model S features a pyrotechnically-assisted pedestrian protection system that reduces head injuries to pedestrians and cyclists in a frontal collision. If the sensors in the front bumper detect an impact with a pedestrian when Model S is moving between 19 and 53 km/h, the rear portion of the hood automatically raises approximately 80 mm. This creates space between the relatively soft hood and the hard components beneath to absorb some of the impact energy in a collision.
Note: The pedestrian protection system relies on a series of sensors and algorithms to determine when Active Hood should deploy. Therefore, the system may not deploy in all collision or crash situations.
If Active Hood has been deployed, the instrument panel displays an alert and an audible chime sounds. Immediately take Model S to the nearest Tesla Service Center. Active Hood’s associated sensors and actuators must be serviced by Tesla whenever Active Hood has been deployed.
Warning: Deployment of Active Hood may cause the raised hood to partially obstruct driver vision. Driving a car with a deployed hood increases the risk of a collision. A car with a deployed hood should be immediately taken to the nearest Tesla Service Center.
Warning: If the instrument panel displays an alert indicating that Active Hood has been deployed in situations where it has not, immediately drive Model S to the nearest Tesla Service Center.
Note: If damage occurs to the front bumper, contact Tesla for a list of Tesla-approved body shops in your area. Tesla approves specific body shops to ensure they meet strict requirements for training, equipment, quality, and customer satisfaction.

With Active Hood technology only existing on vehicles destined for the European and Australian markets, and Tesla being so aggressive about implementing safety features, the natural question is “why hasn’t Tesla made this a standard global safety feature?” An early Euro NCAP crash test video showed that Tesla began working hard at doing everything it can to avoid the accident in the first place. After all, avoiding a collision in the first place is far better for all parties involved than just mitigating what happens afterwards.

Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident

Published

on

Credit: Teslarati

Tesla released Full Self-Driving version 14.3.7 yesterday, and after about 90 miles of testing today, it is evident there are some definite fixes from version 14.3.6, which I wrote about last week and called a regression.

Within the first 40 minutes of my drive on v14.3.7, it saved me from getting into an accident with an unaware Dodge Charger driver, and some of the things Tesla seemed to miss in v14.3.6 were definitely improved. All in all, the release so far has some really great performance, and I’m looking forward to testing it further.

For now, here’s everything I noticed with v14.3.7:

Overall Improvement

Just generally speaking from a ride perspective, this was a really great experience. A lot of the hesitancy I experienced on v14.3.6 was gone. There were no instances of brake-stabbing, wheel-jerking, or any uncertain or unconfident movements. It was void of anything that I felt made it timid with v14.3.6.

The one thing I do hope to see down the road is a smaller need to adjust Speed Profiles so often. Because Tesla calls FSD “Supervised,” I’m okay with needing to hit the scroll wheel a few times a drive.

However, I hope that things can be incrementally improved upon with speed. Sometimes it’s too fast; other times it’s too slow. It’s a difficult thing to hone in and refine, but I hope it eventually gets there.

I didn’t notice any significant left lane camping or any behaviors that were completely out of line. I am hopeful that this opinion does not change, but after driving a few days with this version and putting it in a variety of different situations, you are exposed to more behaviors, some of which are not necessarily what I’d prefer.

The big things to notice, at least in my experience thus far, are that the major issues with previous versions — meaning the braking stabbing and wheel jerking — simply weren’t there. That’s enough to already consider this progress compared to .6.

Manual Signal Override is More Responsive

On .6, I had quite a few issues with FSD ignoring my manually input turn signals. If Tesla wants to call it “Supervised,” then the car should not ignore any input the driver gives. If I touch the accelerator on FSD, the car speeds up.

The car did a great job of obeying my turn signals when I wanted it to change lanes, which is welcome.

Parking Lot Performance

Before .6, I traditionally took over in nearly every parking lot my car entered, because I knew it would not park somewhere that I wanted, and usually, it was just a tad too timid in this setting.

The one bright spot of .6 was how well it handled parking lots. This continued with v14.3.7:

I’m always really happy to see progress at all, but once parking preferences come to FSD, as long as this performance is still around, that could potentially be the biggest improvement I’ve seen in FSD in the year I’ve been using it personally on a daily basis.

Full Self-Driving Averts Disaster

A Dodge Charger changed into my lane without checking if I was there, running me off the road. FSD made the initial avoidance maneuver; I grabbed the wheel out of instinct, looked in my side mirror to ensure I had nobody following closely behind, hit the brake, and straightened the car back up to avoid a curb:

There have been quite a few responses to this video stating that I should never have grabbed the wheel. To be honest, I really wish I had not done so, because I do believe FSD would have avoided any sort of collision with anything, including the car or the curb.

However, this was the first time I had ever been this close to being hit while using FSD. My natural reaction was to take over. I think if I had had something like this happen before, my reaction might have been different.

Hitting the brake avoided hitting the curb, while FSD swerved to avoid the car. My concern after the car was clear of my front end was the curb. All in all, I’m really happy with how things turned out, and I think anyone could be a critic of how I handled it. I only had a split second to really make a decision, and thankfully, any damage was avoided.

It is clear FSD managed to avoid the car coming down before I was able to. I truly credit FSD for avoiding the collision.

What Needs to Improve

Better Recognition of Potholes, Uneven Roads, Sharp Changes in Roadway/Bumps

On Friday, my Fianceè and I were in the car, and FSD was driving us. We crossed over a roadway that has a traffic light, and FSD was traveling at 40 MPH on Standard, 5 MPH over the speed limit. Everything was more than reasonable.

However, the road we were crossing at the light has a major bump both as you start and finish crossing it. Without a speed reduction, your car can go airborne. The Tesla did just this on Friday on v14.3.6; it was an uncomfortable bounce that pretty much confirmed I would not ever let FSD go over again unless we were sitting at that intersection when there is a red light.

I even tried scrolling down into Sloth quickly, but I ended up just taking over:

A few people have said it remains related to the vision-based approach and its difficulty comprehending 3D. This is a huge issue because this can cause serious damage at certain speeds.

Navigation

Nothing new here. I still turn off “Online Routing” quite frequently to get the car to take logical routes from time to time.

Auto Wipers

Auto Wipers are just plain bad. I really hope Tesla just uses a rain sensor. I thought they had improved at one point, but I still get dry wipes, Speed 4 on a drizzle, and Speed 2 on a steady rain. In reality, these should be switched.

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch

Published

on

By

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.

The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.

Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.

SpaceX scores another massive Pentagon deal to support military satellites

Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.

The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.

As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo

SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.

Published

By

SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.

The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.

The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.

Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.
