I don't blame you but this is a classic attitude from someone who has never experienced good transit, so assumes transit always sucks (and weirdly, then concludes we should not try to improve transit). This is like saying hamburgers are bad when you've only ever eaten them at McDonald's (and then mocking your friend who's trying to show you how to make a delicious hamburger from scratch by grinding up good cuts of meat).
> You won't convince a salesman to carry a projector, screen, and a box of pamphlets on the bus and train.
This would not be strange in Manhattan. You couldn't convince the salesman to waste his Time, which is a rare commodity for working people as you say, driving a car which would be slower than taking the subway.
> I'd rather sit and wait in traffic in my car than stand outside in the rain or snow waiting for a bus.
Subways avoid this problem. They're also expensive, but there's easier solutions -- bus and outdoor train shelters (which obviously protect from rain/snow) are sometimes heated in the northeast for this reason too.
Also, dealing with rain/snow is pretty easy and pleasant if you just dress right. The prevalance of cars in this country means many people never learn to dress right because they can get away with never spending more than 60 seconds outside, the brief space between the car and the building door.
> And on top of that, transit for me would be about $400/month.
Here it's $100 a month.
> I'm not sitting on a rough seat crammed next to 5 other people for 2 hours.
A lot of people find dealing with repetitive constant stop and go traffic but having a comfy seat to be a crappy tradeoff compared to having less space but freeing your mind to read, doze, whatever. There are crowded an uncrowded systems and lines.
Go try some good transit, then tell me what you think.
