A Guide to Tesla Model S Long Term Parking

Published

on

One of the many joys that new Tesla owners may come across are situations where they’ll need to leave the vehicle parked for a prolonged period of time and at a location that doesn’t have a charger. The natural thought is, what will this do to the battery?  I inevitably came across this same situation recently and wanted to take this opportunity to share my experiences around it.

“Tesla approved” Spot

Tesla Model S Long Term ParkingMy first mission in any parking lot is to find a “Tesla approved” parking spot. That’s a spot large enough to fit the Model S but also minimize the chance that neighboring cars  will leave me with unwanted door dings. This is especially the case when driving through a busy city like Boston where space comes at a premium.

If I can find a parking space that’s adjoined to a curb on one side, it’s a bonus — I get close enough to the curb (without scraping it!) to maximize the distance to the next space and minimize ding chances.

If I’m making my way to an airport, I know to avoid the busy short term parking garages where the hustle and bustle of pick-up and drop-off traffic is just enough for me to not want to be there. Instead I head towards the long term economy lot where my chances of any unwanted run-ins with other cars is at a minimum. There I look for my “Tesla approved” spot between two already parked cars. There’s a good chance that I’ll come and go before the other cars in the long term lot. Some parking lots also rotate parking locations for new entrants which further reduces the risk of having a new incoming car park next to me.

Minimize Vampire Drain

While Tesla has made some really great firmware improvements to address the dreaded vampire drain, there is still some battery loss when the car is not in use. Even when the car is off and stowed away for long term parking the Model S battery will still discharge albeit at a slower rate as it continues to provide power to the onboard electronics.

You can help minimize battery discharge by enabling “Energy Saving” under the “Power Management” settings on your Model S.  I was able to quantify some of this loss which I’ll describe later in the post.

Energy Saving Enabled for Tesla Model S Long Term Parking

Battery Discharge Notes via Tesla Motors

From the user manual, Tesla says this:

Even when Model S is not being driven, its Battery discharges very slowly to power the onboard electronics. On average, the Battery discharges at a rate of 1% per day. Situations can arise in which you must leave Model S unplugged for an extended period of time (for example, at an airport when traveling). In these situations, keep the 1% in mind to ensure that you leave the Battery with a sufficient charge level. For example, over a two week period (14 days), the Battery discharges by approximately 14%.

However based on my experiences “Tesla math” when it comes to range is often optimistic and not necessarily what you’ll see in the real world.

Real World Experience

Vampire Drain LossI took a short business trip to Las Vegas recently which required me to leave my Model S in long term parking for a couple of days.

It was 11 degrees fahrenheit out when I parked and I had 186 miles of rated range left (71%). When I returned my Model S reported 172 miles of rated range left (65%).

I lost 14 rated miles over the 2.6 days at an average temperature of 16 degrees fahrenheit. So I lost an average of 2.3% rated range per day which is quite a bit higher than the manual indicates. This wasn’t long enough to qualify as long term parking but it’s still important to take note that the rate in battery discharge can be more than double of what you’re expecting. Plan accordingly.

While the loss was higher than I expected, I still had plenty of range to get back home and give my Model S a much needed bath.

Tesla Model S Long Term Parking at Airport

Summary

Be smart and plan out your Model S long term parking strategy, especially if there isn’t going to be a charger on site or nearby. Be sure to have enough battery range upon return so that you can get to your destination or to the nearest charging location.

Tesla suggests a 1% battery discharge loss per day but you may want to consider a more conservative 3% number to ensure you have plenty of range left upon returning.

There are reports of Tesla owners having parked at the airport with a low state of charge only to find  car the the battery was drained upon returning. Bjørn Nyland of YouTube notoriety had an experience with long term parking (27 days at an airport with no charger) which resulted in less than a 1% loss per day – obviously a much better result than I had. The video showed a temperature of 8 degrees celsius, or about 46 degrees fahrenheit which is much warmer than it was for my test which may account for the difference in battery drain.

That said, the Tesla Model S can be safely left in long term parking without a charge and still have plenty of range left to get you home. Just be sure to take into account the number of days the car will be left unattended multiplied by a 1-2% battery discharge per day and you’ll be greeted with a happy Tesla upon returning.

Tesla FSD changed its mind mid-intersection, and it may have saved a life

Tesla shares dashcam footage of FSD Supervised stopping mid intersection to avoid a T-bone crash.

Tesla is putting another Full Self-Driving save in front of its 24.8 million followers on X.

On Tuesday morning, Tesla’s main account shared a dashcam clip with the caption “FSD Supervised preventing T-bone crash.” The footage came from an owner posting as TheNewGrid, who described what happened at a stop sign: “I looked at the car coming to the stop sign figured they would stop, my car went, then came to a stop mid intersection as they flew by. Had I been manually driving this would have resulted in a crash.”

The sequence is the notable part. FSD had already started crossing when the other driver ran the stop sign. Instead of pressing on, the car braked hard in the middle of the intersection and let the crossing vehicle pass in front of it. By the owner’s own account, they had made the same assumption the software initially made, that the other car would stop, and would not have corrected in time.

The clip is the latest in a run of safety posts Tesla has amplified over the past several days. On Saturday, the company shared a video from Selling Sunset star Jason Oppenheim, who sold his Bentley for a Model Y and said he was buying Teslas with FSD for 10 of his employees. Ashok Elluswamy, who leads Tesla AI, followed up by writing that Tesla self-driving “reacts to other people cutting into your path with super-human response times.” On Monday, a Cybertruck owner posted footage of FSD moving across three lanes from a red light to clear a path for an ambulance approaching from behind.

This recent clip also lands a few weeks after Tesla began shipping Automatic Collision Evasion with FSD v14.3.9, a feature that can activate FSD on the driver’s behalf when a frontal collision is imminent or the driver appears distracted. Elluswamy said in September that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” are coming with v15, the release Tesla has tied to round the clock Robotaxi operation.

The safety messaging matters beyond social media. Tesla has said FSD Supervised was 4.1 times less likely to crash than manual driving across 100 million kilometers on European roads, and it has been putting those figures in front of regulators. Eight EU countries have now approved FSD Supervised, with Croatia the most recent, but the EU’s bloc-wide vote originally set for October 6 has been pushed to December at the earliest.

FSD Supervised is still a Level 2 system, and the driver remains responsible at all times. Even heavy users find reasons to step in. Teslarati’s Joey Klender, who uses FSD for about 76 percent of his driving, laid out five recurring issues on Tuesday that still prompt him to intervene. Clips like this one show the other column of that ledger: moments where the software caught a mistake a human was about to make.

Tesla wins over Netflix’s Selling Sunset star, who’s now ditching his Bentley

Selling Sunset’s Jason Oppenheim swapped his Bentley for a Tesla and promised ten for employees.

Jason Oppenheim, the luxury real estate broker best known as the star of Netflix’s Selling Sunset, has parked his Bentley for good and moved into a Tesla Model Y, and he says Full Self-Driving (Supervised) is the reason.

Oppenheim, who founded The Oppenheim Group, the Los Angeles brokerage at the center of the show, posted a video to X on Saturday evening that he called “the most important video I’ve ever posted.” In it, he rides from Newport Beach to his firm’s Los Angeles office, a trip he put at roughly an hour and 15 minutes, while FSD handles the drive and parks the car without him touching the wheel or the accelerator. He said he handed the Bentley to his father because he no longer has any use for it.

Tesla shared the clip from its main account on X about two hours later, pulling out the quote that has since spread well beyond the Tesla community:

“[FSD Supervised] is life-changing. I was on the phone with my brother last night, and I made him buy one. He literally bought one while we were talking. I’m buying 10 of my employees a Tesla with FSD. It’s 8x safer than the average driver. There’s nothing more important than the safety of you and your loved ones.”

Oppenheim was candid about why the safety pitch landed with him. He admitted in the video that he is a distracted driver who answers emails and texts behind the wheel, and framed the employee purchases as a way to keep his team off their phones while driving. Elon Musk posted “Tesla FSD feels like magic” less than half an hour after the video went live.

The endorsement lands at a convenient moment for Tesla. The company delivered 486,532 vehicles in Q3, beating Wall Street’s estimates and marking its best quarter ever without the $7,500 federal EV tax credit.

Tesla FSD has been subscription only in the U.S. since February at $99 per month, and Tesla said in its Q2 update that active subscriptions hit 1.48 million, up 56 percent year over year, with more than 55 percent of new North American deliveries leaving with FSD attached. That attach rate is the figure Ron Baron cited last month when he told CNBC “the time to buy the stock is now.” At current pricing, Oppenheim’s 10 employee cars alone would add $990 a month, or about $11,880 a year, in FSD revenue.

Tesla AI head Ashok Elluswamy said in July that FSD had logged more than 12 billion miles while going roughly twice as far between collisions as manual driving. FSD also remains a supervised system, so Oppenheim and his employees are still required to watch the road, even as Tesla rolls out v14.3.10 with Automatic Collision Evasion, which can steer or brake on its own to avoid a frontal crash.

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.
