I take it you've never cycled in Virginia. I have (on "slow" roads no less) and I've had no less than a dozen people buzz me at over 20 miles above the speed limit.
(There is no such thing as a road where people "don't want" to go fast, because "fast" is disjointed in meaning: there's the legal speed that drivers regularly and unsafely exceed, and there's the "fast" speed at which drivers perceive how unsafe they're being.)
