My guess is since some on car forums like to start crap with people they dont want to get tracked down or seen on the road and get in a fight. Or its possible some thief can see a nice house, cars and how much money someone makes posted on a forum and has a source for DMV info. Or have some creepy forum dude stalk you if you are a woman. I'm pretty sure you can get license plate info if you really want it, depends on the state I would imagine, never really tried myself..

Not to mention the people who post videos or talk about how they went 160mph on a public road and post pics of their car.

Its not the same as people driving down the road and seeing your plate, they have no idea who you are. Why do TV crews blur our faces of people who dont want to be shown.

Why does Google Earth blur out license plates.?

Personally I can care less either way
