I think you should read my comment a little more carefully. 1 and 2 are due to serious physical and economic constraints that are very unlikely to change and apply to all but the absolute most dense areas. Remember, this is in DC. It's unusually dense and is supposed to be the best we have. 3 and 4 are additionally due to cultural, historical, and demographic problems that are becoming worse rather than better and the current political situation is working to accelerate it.
I'm not against transit but it's not the solution people think it is.
