Something else to consider is that traffic was bad way before ride sharing companies started popping up. Secondly, additional taxes will ultimately end up being paid for by people who do not own a vehicle. A better way to help alleviate traffic conditions is to raise gas taxes across the board or maybe just using the tax dollars more efficiently to build public transportation like trains on top of the existing infrastructure that cars typically use. I don't know why California is wasting time on obviously bad legislation. Why do they feel the need to consider the crazy option?
