Was going to post this myself but saw this. +1
Set up a parking lot/garage for people to park in and if they don't use it they get taxed at first, then its open to public, and finally, decays if untouched past a time threshold.
Market looks like crap and no one likes seeing all that junk there that is parked at a weird angle and hasnt budged in weeks.
My only real gripe so far.. otherwise i'm enjoying the game thus far after getting past the wall of tutorial info haha
