That’s true of sedans and hatchbacks too though. Any reasonably sized car is unsafe while sharing the road with the giant trucks and SUVs they’re making to skirt around emissions requirements. I know Kei trucks in particular further lack crumple zones and other protections, but they’re otherwise so practical I wish there was a way to get them approved. Not every vehicle should be built to double as a daily driver.
My long-term dream is a much less car-dependant society, where most people have access to public transit and vehicles like this are there for actual truck purposes.
Speed limits would be a nice change, if only because they could reduce the endless campaign to expand roads to make them safer at higher and higher speeds, but I think it’d be an endless, contentious fight with very little to prevent people (who’ve spent their whole lives dependant on cars for anything they need) from changing them back. I have been impressed with my city for gradually narrowing it’s streets and converting lanes into restaurant space, bike lanes, and I think parks.
