55HP is plenty to travel faster than 25MPH though. The VW Beetle had even less horsepower than that until the 1970s and even then it topped out at 60HP toward the end of their production run. They certainly won't be speed demons but should be fine for most city driving.

An electric option would be good but as someone who works at a campus with tons (like dozens or in the hundreds) of shared Kei-like trucks, golf carts, and side-by-sides, having a place to charge all of them isn't really feasible or safe for all the people who are walking by them all day and night. Here there are just wall outlets strewn about the buildings that they have to run extension cords to and this is just with a fraction of them being electric.
