Here’s a scenario; you’re driving Tesla S autopilot along at 45mph in the left hand lane, when another car jumps out in front of you traveling exactly zero. Chances are, the next decision you’ll be making is which tow truck company to call.

In this astonishing video, that’s exactly what happened. This gentleman’s Tesla S autopilot mode on was cruising along, when another car jumped out in front of him. Before he had time to hit the brakes, the Model S engaged full emergency braking to prevent an otherwise unpreventable collision. Watch the whole video below, I’m literally astonished that this 5000lb electric car was even capable of stopping that quickly, never mind in the rain.
