Uber and Lyft are not a good solution. I could every trip on them as worth a weeks worth of driving alone since you don't know where those drivers are driving (or sitting stopped waiting for a call) when you call them. If everyone is normally using transit they are okay - but then there should be all day service to the campus so you don't need them. (I will agree if you say I'm over counting their environmental costs - I do that to make a point that is often ignored)
