risking jacking over 2 tonnes at the road side...

I'd never stop my car on the road unless it was completely dead. I'd rather (and have) drive on a rim and get off the highway.

It might depend on the area, but my '24 did come with a jack in the frunk.

I have one in my '21 and my '24.

my last gas(non hybrid) sedan was from 2011 and it had a curb weight of ~ 2.1 tons - funny that the jack came in that one was only rated for 1.8 tons for some reason, worked fine for quick tire changes tho

When you jack up the car on one side the entire weight of the car is not on the jack. At most maybe half.
