The Tesla Effect: Why EVs will take a big bite out of oil demand
The newly defined “Tesla Effect” is producing remarkable consequences. Tesla electric vehicles (EVs) have changed the way that people all over the globe now think about transportation, the place of zero tailpipe emissions, and an accelerated agenda for sustainable energy. One “Tesla Effect” is that the International Energy Agency last month forecast that global gasoline demand has all but peaked because of more efficient cars and the spread of EVs.
Thank you, Tesla.
As a small Silicon Valley startup, Tesla Motors began with a line of luxury electric sports cars that could reliably produce more than 200 miles on a single charge. Due to the wide acclaim and demand it received for its cars, Tesla was able to repay a 2010 loan from the U.S. Department of Energy a full nine years early. Their manufacturing facility in California became the largest auto industry employer in California, and Tesla was soon spreading its mission around the globe. It has achieved success beyond any expectations — except that, perhaps, of CEO Elon Musk — and has prompted other major automakers to accelerate work on their own electric vehicles in order to maintain currency in the market.
And now, while EVs represent less than 1 percent of total vehicle sales, they are predicted to soar in popularity around 2025. That’s when many governments around the globe, including Athens, Madrid, Mexico City, and Paris, have pledged to phase out diesel vehicles in a battle against pollution. These promises, known as “intended nationally determined contributions,” will have significant consequences of their own over the decade that will follow. By 2035, EVs may remove 1 million to 2 million barrels a day of oil demand from the market.
“Anything that reduces the demand for transportation has an impact on the oil market,” Alan Gelder, vice president of refining, chemicals, and oils markets at Wood Mackenzie, said in an interview in London. “The question is how big is it going to be and what’s the time frame.”

Electric cars are displacing about 50,000 barrels a day of demand now, according to the oil industry consultant, Wood Mackenzie, which promotes itself to potential customers as “embedded in the industry, with more than four decades building relationships, improving performance and keeping you ahead of the competition.” To placate nervous clients, Wood Mackenzie says that it does expect total oil demand to keep growing for decades, driven by shipping, trucking, aviation, and petrochemical industries. That’s more conservative than Bloomberg New Energy Finance’s forecast for EVs to displace about 8 million barrels a day of demand by 2035.
Tesla alone won’t be able to supply enough EVs if demand really takes off, Gelder said. Major automakers including Volkswagen AG and Ford Motor Co. will need to produce them on a larger scale. “At the moment they can’t, and changing manufacturing lines takes time.”
Gelder continued his argument by stating that regulation and government subsidies alone won’t be enough to spark a boom in EVs. Consumers, he insisted, will need to believe that EVs are preferred for a variety of reasons. “If there’s a technology revolution, so battery technology gets cheaper and EVs don’t need a subsidy, then it comes down to consumer preference. If the consumers like something, it’ll switch far faster.”
If the global response to Tesla is any indication, EVs are not only here to stay: they’ll be the preferred individual mode of transportation of the future.
Tesla just upgraded its headlights through a software update, making them even better without any physical or hardware upgrade.
Tesla’s latest software update is quietly improving nighttime driving for a small number of owners. Version 2026.38 includes a new capability called Dynamic Headlight Leveling.
The feature automatically adjusts the aim of the low beams in response to driving conditions and nearby traffic, with the goal of giving the driver more usable light on the road while reducing glare for oncoming vehicles and traffic ahead.

Unlike Tesla’s matrix high-beam system, which selectively dims individual LED segments to create shadows around other cars, Dynamic Headlight Leveling physically tilts the low-beam projectors. Internal motors respond to changes in vehicle pitch.
When the car accelerates hard, climbs a steep grade, or carries extra weight in the rear, the headlights can otherwise point higher than intended. The software counters that movement in real time so the beam stays aimed at the road surface rather than into the eyes of other drivers.
Early indications reveal the update is reaching a limited set of vehicles, including certain Model 3 and Cybertruck examples in the United States and the United Arab Emirates. The rollout does not appear tied to a single hardware revision, and Tesla has not published a broader schedule. It is simply a common waiting game until your car receives it.
The change arrives against a backdrop of wider complaints about headlight glare. Some earlier Model 3 and Model Y vehicles were the subject of an NHTSA recall related to excessive low-beam glare; the software adjustment offers a potential mitigation for cars equipped with the necessary leveling hardware. It does not replace adaptive high beams where those are already available, nor does it alter the basic low-beam pattern itself.
Instead, it keeps an existing beam pointed where it is most useful.
For drivers who have received the update, the system requires no new settings or user input. The headlights simply respond as road conditions and traffic change. As the feature reaches more vehicles, it adds another example of Tesla using over-the-air software to refine existing hardware rather than waiting for a new model year. Nighttime visibility and reduced glare for others are the practical results owners are expected to notice first.

Tesla teases “Halloween Mode” update with Optimus rising from a graveyard
Tesla’s Halloween teaser hides a covered vehicle and an Optimus hand rising from the ground.
Tesla has started teasing a Halloween software update for its vehicles, with a short clip on X that reads, “Halloween is coming.” The clip opens on a glowing pumpkin before pulling back to the car’s center touchscreen, where the usual parked visualization has been replaced by a graveyard scene, and the vehicle draped with a white sheet so it reads as a cartoon ghost.

The second detail is a robotic hand clawing its way out of the dirt like a zombie, which looks to be the hand of Tesla’s latest Optimus V3 humanoid robot. While Tesla still has not formally shown Optimus Gen 3 walking around in service, renders pulled from Tesla’s Android app last month gave the clearest look yet, including far more refined hands that Tesla has said carry 22 degrees of freedom. The hand has been the hardest part of the program. Musk has called it the majority of the robot’s engineering difficulty, and Tesla’s patents describe a design driven by tendons with the actuators moved into the forearm.

Optimus also has a Halloween track record. Last October the robot handed out candy in Times Square, and a costumed “zombie” Optimus shuffled around the Tesla Diner in Los Angeles on Halloween night.
On the software side, Tesla’s 2025 Holiday Update expanded Santa Mode with a Santa sleigh, snowmen, snow effects, and a festive lock chime, so it wouldn’t be too far fetched if we saw something similar but themed for a Halloween Mode.
Tesla Full Self-Driving is set to receive improvements to address its two biggest issues, according to a company engineer.
Director of Engineering at Tesla AI, Phil Duan, revealed in a post on X that improvements to both pothole avoidance and navigation “are coming,’ something we have heard many times in the past. However, there are a few things that seem to hint that things might be different this time around.
Improvements on both are coming.

Pothole avoidance, navigation, speed control, and left lane camping are some of the most prevalent and frequently mentioned shortcomings of the Full Self-Driving suite. These are a few of the biggest issues that have kept Tesla Full Self-Driving as a Supervised suite, meaning drivers must remain attentive during operation.
Pothole Avoidance
Pothole avoidance was first mentioned as an “Upcoming Improvement” with the Tesla Full Self-Driving v14.3 update back in early April of this year. It was listed alongside “Expand reasoning to all behaviors beyond destination handling.”
It’s been six months since we first saw pothole avoidance explicitly mentioned, and it has not moved beyond that and joined the main release notes yet.
Tesla has not shed any light on why pothole avoidance has been such an issue for it to solve, but it also has issues identifying large bumps much of the time, so its modeling of sudden changes in road conditions is likely pretty weak at this particular point. I’ve had more issues with large bumps than potholes, personally, but both are issues that need to be resolved.
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

It makes sense that things might be pretty close to being released to the public, as we are going on such an extensive period of time between it being mentioned and it actually being deployed.
Navigation
Navigation is likely the most painful part of using Full Self-Driving, as it routinely takes strange routes, has trouble with local rules (like Except Right Turn Stop Signs in Pennsylvania), and sometimes does not realize that maneuvers it is suggesting are against the law. Turning out of my neighborhood, you cannot turn left, yet my Model Y still suggests it roughly 70 percent of the time when I’m leaving.
However, Tesla might be close to a breakthrough on this. With the Summer Update, Tesla added “Preferred Routes” alongside “Automatic Navigation.”
Preferred Routes prioritized roads that the driver had actually taken before, instead of always defaulting to what the vehicle believes is the most efficient path. This has already solved many of my issues. Formerly, I would turn off the Online Routing setting, and that would eliminate most of my complaints with routing, but then you lose out later on the Live Traffic Visualization.
Tesla’s Navigation has improved tremendously thanks to the Preferred Routes release with the Summer Update, but it still could use some polishing, as it still suggests strange routes from time to time, and it also has a lot of issues getting out of a parking lot. I find that those truly confuse FSD sometimes.
