We've seen videos of people reacting to the all-electric Tesla Model S P85D "Insane Button", but it's just not complete until we can see it in slow motion.
When the 'Insane' mode is initiated, the vehicle can accelerate from 0 to 60 mph in just a little over 3 seconds -- fast enough to send any full grown adult flying back in their seat.

Thankfully, Defensive Driving put their GoPro to good use, and filmed some great passenger reactions to the high-speed acceleration from the vehicle in slow motion.
