I have a 1990 Subaru Sambar pickup truck [1] imported from Japan that is street legal and registered in Washington state. It’s probably only a tiny bit safer than a motorcycle because it has seatbelts. Maybe cancelled out by the fact that I don’t wear a helmet while driving it.
You can get them for $3K - 5K depending on condition and they are excellent little city trucks that get fantastic fuel economy. Getting used to the right-side drive and shifting left handed wasn’t so bad. The hard part is the blinkers and windshield wipers are swapped!
