Its newer cars with drl lamps, with the faint glow coming from the front, they just presume their headlights are on. The fact that most dash boards light up like a Christmas tree when you turn the ignition on doesn't help either!

See a lot more cars these days with fog lights on in the dark, think the fines should be higher for misuse of lights etc.

People who also leave their wipers on full speed when the rain stopped 10 minutes ago, do them for lack of due care and attention!
