These Apps Want To Be The Airbnb Of Your Driveway

Back when I was a cash-strapped college student splitting an apartment close to campus, on football game days I'd stand outside with a handmade sign in magic marker advertising to rabid fans: "Parking - $40." On a good day I made $80 all together, renting the unit's parking space and the alleyway next to it -- which I'm not sure was a parking spot and I definitely know wasn't mine to sell anyway.
