I have so many problems with this, I don't know where to start. A guy decided to race a horse in his car and instantly regretted it. There's only one thing I like about the video of this that has gone viral.
I used to be a delivery guy for FedEx and have had some weird things happen to me while making some deliveries. Nothing quite like this though. Poor guy got chased around by a dog who was probably just being playful/protective. I could be very wrong about assuming that.
