Why aren't we doing this

Its awful to go on public transport.

People have cars for the same reason people like their own apartment or their own house. Other people are awful to be around. They will have no problem making loud noises, caughing at you, smelling bad… People dont care, at all.

People actually pay very much to own a car, and why do they do that? Because public transport is a horrible experience. Im addition to the things above, it takes you at least 2-3 times as long to get anywhere using public transport compared to a car.

I really hate it, no joke. Cant stand using it for more than maybe once per month if I have to.

Driving requires you to be constantly alert, and if you screw up or don’t react fast enough, you can straight up die because of it. On a bus, you can be on your phone, read a book, take a nap, whatever. Driving is a much worse experience and even if public transit takes more time, that’s time that can be used doing things. That’s before factoring the cost (the car itself, gas, insurance), the environmental impact, parking, etc.
Sounds like you like the bus, thats great. Good for you.
