This Mercedes driver has plenty of room to merge into traffic, but chose to stop at the yield sign - even though there is no traffic coming. This instructional video shows the dangers of not being aware of road signage, traffic, and rules of the road.
Do not engage in road rage. Do not get out of your car in the middle of traffic. If you get out of your car do not leave your transmission in drive. When you notice your car driving away without you, do not step on the accelerator instead of the break. Notice how instant karma gives him a sharp knock in the head with his door!?
