Maryland also has the world's worst drivers.
This is the sole reason I can't stand Maryland. I grew up in VA, lived for a few years and still work in MD, just moved to DC (so, can't comment on that).
But wow, Maryland drivers are the worst I have ever seen. It's the king of one car accidents. I don't go more than a week without seeing a carbeque on the side of the road just blazing away. Everytime there's a merge, construction, an exit/entrance-ramp, or if the interstate takes the slightest of turns everyone slams on their brakes, changes lanes like 8 times, speeds up abruptly only to do it all again in 50 feet, and generally freaks the fuck out.
Yeah, Northern VA is a mess and DC is a bit of a disaster with the tourists and strange intersections, but they've nothing on Maryland. I'm not sure if it's the lack of annual inspections which allow for complete wrecks to be on the road, if their licensing tests are inadequate, lack of enforcement for traffic idiocy fines, or what.
