We have these trucks in Taiwan. It's quite literally the majority of the trucks on the road. These things are not allowed on the highways because a crash in them will result in likely death.
Instead they are only allowed on local roads where our speeds don't reach anything more than 40km/hr. Even then, the crashes I have seen in them, the driver is always hurt.
I know Lemmy likes to dream about owning a kei truck. But keep in mind that these trucks are not safe in crashes. They were never designed with the speeds that Americans see on a daily basis.
