> The car is designed for urban settings

Huh, the speed limit is odd because in my urban/city driving in the western US (San Diego, LA, SF, Portland and Seattle) all major cities still basically necessitate non-zero highway driving. Even mopeds (and bicycles) can pretty easily exceed 31 mph.

I've spent about 2 months total in Mexico City and there are still in-city areas where it'd be common to exceed 31 mph. The main rate limiter being traffic...

Anyway not to pooh-pooh the idea too much, I am sure there are plenty of use cases but maybe enabling a top speed of 55 mph would increase utility IMO
