Interesting that you bring up parking lots. A parking lot is basically a privately owned piece of pavement. What else is? Well, for starters, a driveway.
Come to think of it, if my driveway were more than two car-lengths long, I could probably speed as much as I wanted until I got to the road. The police don't put speed traps on driveways.
"So what?" you ask?
So, don't build a "Race track" to try and make money on (or even break even). IF you invest in all that land, build a freaking house, and make whatever kind of driveway you want. Here in suburbia we have oval-driveways, so your "driveway" could be modeled after the ring.
Good plan if you're an eccentric millionaire who can independently afford to build and maintain miles of high-quality pavement with precisely no return-on-investment.
