So these are wonderful, if you do not consider that they will have to share the road with actual cars which can easily pancake them and kill the occupants.
With the advance of batteries, power electronics and electric motors, there all kinds of cool new modes of transportation coming up but they are all kind of metaphorically and sometimes physically crashing against the concept of cars and the fact that all of our streets are basically made for cars.
I think we have to start seriously rethinking cities in view of these new modes of transportation. I would suggest a city center where there are no cars and bycicles and various slow speed electric vehicles, like scooters and glorified golf carts are allowed to roam. And then you can have the suburbs where full sized cars (electric or not) can drive but will have to have full modern crash protection.
Something like this is already starting to vaguely happen in some cities in Europe. It is of course easy to do in some european cities where the streets in their centers were pre-industrial and never designed for cars to begin with. But it is something to be expanded.
And it will be very helpful if large international manufacturers created a "glorified golf cart" standard that was reasonably safe for pedestrians and bicyclists (again assuming that it does not have to share the road with cars) so that the cities around the world can start doing city planning around it.
This "$5k electric car" is a glorified golfcart pretending to be a car, which is quite dangerous, because people will treat it like a car and will all to late realize how bad it fares when it crashes with actual cars.
