@jenniferplusplus That may work in places with adequate public transit infrastructure already, but in most of America, if we want people to use it, we need to build it first, and the money would be better put towards that. No tax credit is going to get me to use a bus that only comes every two hours and has stops more than a mile from my origin and destination.
So many of us in cars would be happy to use public transport if it just didn't suck so bad.
