A few parking tickets (which is what it sounds like you want with the cop example on your OP) isn't going to make people switch from driving to SEPTA. It also won't make people stop driving altogether. Some of us rely on our cars to get to work, because there is no transit nearby or several transfers and 2 hours to get to work versus a 30-minute Drive will never be appealing. It's survival, not self-interest, and when you have kids it's a matter of caring for other people, because I have yet to find a daycare open past 6p.
