Oh ****, exactly the same thing happened to me. To my luck, the motorist, who simply "didn't see the bike parked there, in a designated bike parking space", went into a convenience store to buy something. The proprietor noticed and immediately went out to the curb and drew his attention, and together they lifted the bike.
My bike has an anti-theft system that makes my phone beep every time it's moved, so I knew something was wrong and was there before the driver was able to take off.
Took some pictures, exchanged details, and he paid off for the damaged throttle grip and break lever, which were replaced the following day.
True, people suck, but distracted, oblivious, irresponsible drivers suck more!
Glad the damage is just paint and a few inexpensive parts.
