Bret Michaels -- Rams Lady In Broad Daylight!!

Bret Michaels continues to prove he'll bump em' no matter what age ... even in the middle of the road.

An eyewitness says Michaels was cruising in a Mercedes in Scottsdale, AZ Friday morning when he got just a little too close to the car in front.

We're told not a lot of damage ... Bret exchanged info with the woman and the two went on their own way.
