they did not check if the vehicle was stationary, motor disabled before updating. They were all surprised at how I thought that this could possibly ever lead to issues.

My anecdata is that my car won't update its software without the owner explicitly requesting it. And then, it will only do it if the car has something like 50% charge, hasn't been used for an hour, and nobody is inside.

I once tried to do the update while I was inside, and it refused.
