Exposure to disease, Loss of transport due to strike or weather, dealing with the low IQ or drunken morons riding public transit, the smell and the filth...Just some of the reasons I'll never ride on public subsidized transit.
A car eventually is paid for and your kids will reap the benefit of a classic car price when they sell it decades later ,Providing you buy a car and not a toy, transit is a cost forever, ever rising and ever less efficient and has no end value.
1972 Chevelle SS cost about 4 grand, today 80,000 at auction. 
I pi55 on public transit and pay for it through taxation by force of law only, it disgusts me.
12% of the population in the 1980's rode transit, today 12% of the population rides transit, complete waste of taxpayer dollars.
