I use regional rail as often as I can because I hate fighting traffic in and out of the city. However, regional rail is relatively safe, clean, and without drama. Other forms of public transport can be not so nice. It is not about oil company profits, but some people just don't want the issues of dealing with other people in a commute. They prefer the privacy and safety of their cars. I have no problem using my metro areas rail, EL, trolley, and subway system.
