Kei-cars are the smallest class of cars allowed on highways in Japan. Japan highway speeds are quite low at 100km/h, which is still more than twice what this car is limited to.

On intercity highways in Japan you are driving next to as large trucks as anywhere I've driven.

The roads are built to accommodate the cars Americans drive. At minimum, we have to put our money and interest towards alternatives for the system to change.

This newly announced truck is apparently limited to speeds I'd consider borderline unsafe on American public roads (<= 25 mph) because that puts it in the LSV category, and that's apparently the only way you can sell a Kei truck under current US regulations. So they're making it less safe and less useful in order to be able to sell it here, I suppose thanks to reasoning similar to that which appears in your comment.

IIUC a typical "real" Japanese kei truck can manage 60-70 mph easily, if not comfortably. That's more than enough to hang with traffic on the vast majority of American roads, and nobody sane is using these things as long distance transportation. So the "they're too slow" argument is clearly bunk.

That leaves the safety angle. I can't help noticing that motorcycles are still legal, or did I miss something? Anyway, it's very emblematic of the American approach to road safety that some small, light vehicles are uncertifiable on safety grounds, but the sizes and weights of personal vehicles are allowed to grow in unbounded fashion. There is clearly no safety issue with getting groceries and picking your kid up from school in something that weighs most of 10K lbs and has such dogshit sight lines that you could run over a whole school bus's worth of kids in a crosswalk and hardly notice.

Freedom? Personal responsibility? Not quite---you can make a choice to endanger other road users, but never yourself! Unless you ride a motorcycle, in which case that's okay.
