Yeah, when I started looking at them, the sales guy at a dealership directed me to where I could find an on-ramp to bomb around. (After going very slowly to get there, past the usual speed traps.)
Since then, I've moved to an island on the west coast. Roads are where the terrain allows, and nothing is straight or on a grid. Perfect!
I only wish I had spent more time driving it more interesting places, instead of to work in that wretched city.
