There are some issues with alternative transportation in some areas... Like mine. My son lives in Boston and gets a transit pass as part of his salary, if he drove he would have to pay substantial money for parking. In the larger town near me mass transit is a joke, it doesn't really go to or from anywhere and doesn't run when people need it if you have any sort of shift job. If I happened to have a job downtown and the company had to pay for my parking it would cost them a whopping $40 a month. Until the taxpayers revolt and make local governments stop subsidizing free/low cost parking it will continue, uphill battle IMHO.
