Nope, the Smart existed for quite a while. Safety standards made cars slightly bigger (e.g. the new Renault Twingo is bigger than the original), but modern American "cars" are massive because that's what marketing has convinced Americans it's what they need. American vehicle manufacturers are pretty terrible at everything, and efficiency standards nudge them that way anyways, so making massive cars with high margins is a good deal for them.
In Europe there are SUVs, but the average car is a VW Golf or a Renault Clio sized. They are pretty decently sized, good visibility, can fit a family of 4, etc. Yeah, you can't haul a 50 ton campervan offroading up to Kilimanjaro, sure, but that's not what 99% of car trips are for.
> I think we will see small, light weight and intrinsically pedestrian safe cars made of tubes and canvas replace the heavy monstrosities we have now.
Renault Twizy ( https://en.wikipedia.org/wiki/Renault_Twizy ) exists, but doesn't sell all that well (compared to "normal" cars).
The Citroen Ami ( https://fr.wikipedia.org/wiki/Citro%C3%ABn_Ami_(2020) ) is pretty popular in certain places (saw a ton of them in Amsterdam and semi-rural areas in France).
