EVs aren’t uniformly heavier than ice vehicles. Median weight is 2145kg vs 1768kg for ice. Your driveway should be able to hold around 8000 lbs, or 3600 kg. Basically the only ev you need to worry about is an electric Hummer.
And, again, if you feel your driveway can’t be used as a driveway, it’s already broken. The point of the thing is for people to put cars on it.
You’re welcome to put signs up on your own property for whatever you like, but you look silly getting upset for something like that.
It’s like putting up a sign demanding that people don’t knock on your door because if they do it’ll fall off the hinges. It’s your right, but don’t be surprised if people don’t look for the sign, and maybe just get something that isn’t broken.
