> Public transportation in the US is at best, tolerable.
I think this is very dependent on where you live, in both DC and the Bay I think public transportation is good, but expensive. To me, the problem more appears to be an American cultural aversion to intermingling the working class and the "professional" class of people.
> 2.) Bicycles are awesome, but you have to contend with precipitation, sweat, and theft.
Every mode of transportation has some downsides. You could say 'Cars are awesome, but you have to contend with about ~40k people dying in crashes every year.'
> 3.) Living close to city centers is abominably expensive
Hm, maybe if we could densify cities by removing some of these large paved spaces that people are supposed to stay away from.
