Kaley Cuoco Big Bangs Dude From Behind ... He's Not Complaining

Kaley Cuoco got up close and personal with a fellow driver in L.A. -- and his Mercedes-Benz paid the price.

The 'Big Bang Theory' star exchanged information with the guy after she apparently rear-ended his ride with her Range Rover on a street near her home. Based on the pics, doesn't look too bad ... fender bender-ish at worst.

We're not saying the guy enjoyed getting hit from behind, but if you're gonna have an accident -- might as well be with a smoking hot TV star. Perks of life in L.A.
