Electric Vehicles

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.
