The government of Dubai installed a rather large speed bump on a street that locals had developed a habit of travelling on at very high speeds. Only one minor problem, the government didn't tell anyone it had installed the speed bump. Without a sign of warning vehicles hit the mound and leave terra firma, only to land in a shower of sparks as their suspensions bottom out. The final car in this video, a Lamborghini Gallardo, nearly flips tail over nose when it hits the speed bump, which, again, is why we only drive ours on the track.
