Does roadside assistance (AAA, etc) not offer some kind of "I ran out of gas" service for electric cars?

Edit: As of 2022, AAA actually does have emergency mobile charging. But of course, only in select cities. https://newsroom.aaa.com/2022/12/electrifying-aaa-member-ben...

Cars break down all the time but at least they can be moved to the side of the road. Are Teslas not able to be moved once they run out of juice? They’re heavy and even with a few folks pushing from the back, is it able to disengage the parking brake?

From the fine article:

> The handbrakes of electric cars, and some other modern cars, are controlled electronically, unlike those of traditional petrol and diesel cars, which are mechanical. This means that the handbrake often locks when the power fails and the car cannot be pushed or towed.

This sounds like a major oversight by Tesla as there should be some override in case a vehicle breaks down in a dangerous position or is blocking something important.

Running out of fuel is something it’s obviously “easy” to do with other cars.

But I’m surprised that the electronics have _no_ power redundancy, there isn’t a manual release for the parking break, and running out of power causes the parking break to fail-closed?

"The Tesla Model 3 Performance is a four-wheel-drive electric car with a starting cost of £57,000 and a battery life of 41 hours."

From the article, I had no idea battery life was measured in hours, I don't even know how that would work for a car.

They do (I've seen photos of assistance service cars with a bunch of batteries tacked on in the back), but it's a very new thing and not very common yet.

Also the assistance service cars are mostly petrol based still, but even for electric ones I've been told it's non-trivial to wire the existing batteries out (… safety mechanisms and whatnot), making extra battery packs the go-to.

My diesel and my wife's petrol card both have electronic handbrakes. I'm not sure what would happen if either has a battery failure.

They can be towed, but it is correct that certain electrical failures can prevent the brakes from being released.

I know because this happened to me. The tow company sent a flat bed truck and used a winch to pull the car onto the platform.

It’s pretty annoying from a design perspective but it also seems like something that any competent tow company should be able to handle easily.
