I've seen a few examples of this recently. Tesla owners are parking their car, often on a slight hill when it's been snowing and the car just slides away once the owner is out of the car.

See here:


Here with added fireworks:


And lastly...


Not sure if this is just a Tesla thing due to low centre of gravity/even weight distribution/weak parking brake? Perhaps it affects all cars, but I haven't come across it before if so.

What makes it extra worrying, as in video #2, if you are plugged in you'll likely take the wall charger with you! Luckily my driveway is flat, it it wasn't, I'd be investing in some chocks.

Not sure if this is just a Tesla thing. But I guess once the car is parked the weight can, in certain conditions, melt the snow and ice to form a very slippery surface under the wheels. This could be enough to get the car moving. Once it is sliding it may well keep going. Surprised I haven’t heard of it before though. Chocks wouldn’t help much unless they had teeth like crampons!

I'm a bit surprised with the video 2 . When connected to my Tesla wall charger at home or to a Supercharger, I can't put in drive mode and got a message with the Model S.

It would seem someone in Glasgow last night / this morning wasn’t having a good time. (Was sent the video by a friend and stuck on YouTube to share)


Edit: I noticed you could see the people in the cars face in the original so I’ve edited it to cut the first bit out.

In this case there's no one in the car, the car is not in drive, the car slides away from its parking spot whilst in park.

Its people with summer tires not understanding how poor they are in the snow/ice. Nothing to do with Tesla, beyond them shipping summer tires on the Performance versions (like many other manufactures do)

It's perhaps because of Regelation. Pressure reduces the melting point: Regelation - Wikipedia

Very unlikely .. it used to be thought regelation was what made ice skates work (it isnt), but you need a lot of pressure and a lot of time for it to work at all, science class demos notwithstanding :)

This looks to me like simple friction issues. You have a heavy car, but tires with pretty high pressure (means low tire area in contact with ground). The OP didn't state conditions or driveway angle, but for a lot of these videos the road angle looked pretty steep (and videos can often make slopes look much flatter than they are). Any car will slide under the right circumstances, just go look around on YouTube.

I can't help thinking in the video applying a bit of physics might have helped him.. he was braking with no grip.. that's not going to help. Best to let the wheels roll and hope there's enough grip left to direct the car down the middle of the road.

Whether there was any way of salvaging it at the bottom though..
