Okay, you're right about the Wikipedia article not showing an increase in those statistics for mass transit. However, this paper does show a substitution effect for busses: http://clinlawell.dyson.cornell.edu/InTech_public_transit_chapter.pdf http://clinlawell.dyson.cornell.edu/InTech_public_transit_ch...
