For instance, my 20 year old Land Cruiser (Which I, perhaps engaging in a bit of semantic pedantry would call a 4x4, not a SUV) has a dry weight of pretty much 2 tons / 4,500lbs.
A Nissan Leaf? 1,600kg/3,500lbs. (Tiny compared to the LC)
Tesla Model S? 1,950-2,300kg / 4,300-5,000lbs (Still small compared to the LC)
And high cars can roll over lower cars, making the deformation zone have no effect.
Interesting anyway about weight.
I'm thinking high cars should be forbidden ... Unless in terrain on the countryside.
In Europe there are some sub-500 kg cars (eg Renault Twitzy). Not that this should be the limit necessarily, but there's plenty of room downwards in the design space.
I noticed more SUVs than ever last time I visited my parents-in-law. But where I live myself, the number of parking spots is shrinking and streets are being narrowed. A divide seems to be growing.
I hope this works, but I've noticed more wide vehicles in my neighborhood parking with two wheels up on the sidewalk, like this.
A neighbour called them when a so-and-so parked so closely to our entrance that I couldn't get the bike trailer out. The towing company took a few photos, towed, and sent the so-and-so an invoice for €600, which he eventually paid, but not without telling my neighbour what he thought.
€600 is steep. They must expect to pay for court cases fairly often. Makes sense, parking like that was very rare 20 years ago.
In fact, my driving experience so far is that smaller cars are more likely to wait if it's too narrow, but people in larger cars barrel on thru bc they know that they'll intimidate drivers on the other side.
You say that like it is a bad thing? The future sounds awesome!
But I guess that in the future, no one will drive themselves anyway. Whether due to automation or cost.
