Chris Brown -- Gets Smart ... Dodges Possible DUI? (VIDEO)

Chris Brown is a responsible adult -- let that sink in ... and then watch him make maybe the smartest decision we've ever seen him make ... on camera, anyway.

Chris voluntarily handed over the keys to his brand new $200k Rezvani Beast on Sunday ... right after walking out of Penthouse nightclub in West Hollywood.

It's pretty amazing and commendable to watch unfold -- Chris actually jumped behind the wheel of his exotic supercar, ready to roll.

But watch, there's a quick discussion with a friend ... and then the hand-off to another friend.
