Jalopnik, another automotive blog, posted an interesting article on speed limit enforcement by state, including a nifty graph showing the states issuing the least (and most) tickets.  Washington, D.C. tops the list with 78.5% of tickets per-capita.  Anyone who has ever been to Washington D.C. knows how easy it is to be ticket, not to mention how expensive a ticket can be.  To further compound the matter of the voluminous amount of speeding tickets, Washington D.C. also notably is one of the few places that prohibits passenger vehicles from having radar detectors.
