I remember these lines on the cover of the Beatles' Abbey Road album. I thought they were painted there for the photo shoot.

Turns out they're actually lines in the road with actual meaning to those who drive on the wrong side of the road. (If Brits drove on the right side, they wouldn't have to paint every crosswalk with "Look right" or "Look left" so pedestrians didn't die trying to cross after looking the wrong way. Sorry, I digress. Apparently these zigzag lines are painted on either sides of crosswalks (which are not at corners). They mean that drivers are not allowed to stop or park there so that pedestrians have a clear view of traffic in both directions. Learn something new every day. :)
