Another challenge I could see is the chicken and eggs cold start problem. Until there are enough people willing to rent their cars out, the supply would be minimal and no one would even consider this when flying. I can't see any easy way to bootstrap this marketplace. Uber could bootstrap their marketplace because there are a lot of repeated business in downtown, and even then it took a huge amount of capital to do that. Maybe it's Thursday late afternoon blue, but I am seeing less and less start ups from YC that really make me go "wow, what a neat idea to solve a problem that's been bothering me". Now all I am seeing is a lot of solutions going around looking for a problem.
