The garbage truck driver comes sprinting out as I notice the truck staring to creep backwards. He jumps in just in time for it to run over the electrical box cutting all the power to the gas station. Sparks flying everywhere and 5 seconds of high current noise. Guess this is a lesson that parking mode would help me with these things if I enable it.You can see the frustrated driver as I leave. The truck was stable on the hill for 2-3 minutes without rolling backward, all of the sudden it just let go and started rolling.
