Buses, electric wheelchairs etc.
Buses don't go to a house, they go to a bus stop, and the point is that there are people in society too sick and frail to walk a block. You're not about to put a 90+ year old in an electric wheelchair and tell them to wheel home from the bus stop in the rain or snow.
Yeah cars suck, but it's deluded fantasy to ignore their clear application. How are you getting your kids and all their sports gear to practice in the winter? How are you transporting building materials to your house or condo through snow?
End of the day if you design bikes to handle that kind of stuff you'll quickly end up adding more wheels to help balance, a roof to cover you in inclement weather, and more power and suspension to help drive it all, and you've suddenly designed a car.
