This is a video of a Koenigsegg Agera RS supercar going from 0 to 403km/h (250.4MPH) and back to 0 in 37.28 seconds. Impressive, although I definitely think they could have shaved some serious seconds off the 250MPH back to 0 time with a really sturdy wall.

Keep going for the video, actual cockpit view of the trial begins at 1:50 (the rest is just buildup).
