I'd guess my place is about 95% car-single occupant.
I was going to +1 this, but I think it's more like 99.5%
Even folks like me who bike commute - I only do so 2 days/wk and not when the weather is bad.

Bacchetta Giro (recumbent commuter)
Bacchetta Corsa (recumbent "fast" bike)
Greespeed X3 (recumbent "just for fun" trike)
Strada Velomobile
I will never buy another bike!
