You are right for most people. I am not (and cannot get) fit enough to walk and ride everywhere. I walk as much as I can because cars suck but I appreciate the car. You got me thinking about ebikes. Speed is also a thing though. Getting somewhere in 2 minutes instead of 10 is very convenient.
My friend has a velotric T1 and it's really great. Definitely get an ebike. I got a reflective jacket on ebay for $20 so cars can see me at night. Ebikes are just as good as normal bikes ( it took me years to realize this ). I have an EUC so I wont get an ebike fore now.
And yeah if I end up having kids, Ill get a minivan or something for chauffeuring. Sometimes you do in fact, need a car
The best cities have laws that allow for light motorized vehicles in the bike lanes. Not just ebikes, but also mobility scooters, microcars, electric wheelchairs, and adaptive bicycles.
