This driver is playing his guitar while driving. That’s right, a full size guitar. If you look carefully at the picture, you can see the part of the guitar’s head and tuning pegs sticking out the driver’s window while he plays.
Talking on the cell phone? Applying makeup? Eating an In-N-Out burger? Drinking a Big Gulp? Nope, I’d say playing a guitar is pretty much the most unsafe thing a driver can do in a car while driving, alone.
