The guy on this motorcycle is very talented and extremely observant!

 

The guy on the motorcycle spots the coffee cup and tries to catch it (he finally gets to it at about the 30 second mark). However, his biggest problem is trying to get the lady's attention who left it on her bumper. He keeps driving up close to her and waving the cup but she's almost oblivious. It's finally when they turn the corner that she realizes he's trying to get her attention and gets the cup from him.

What's even worse!? She immediately dumps her coffee!! haha
