Today we rode up to Pikes Peak, which has an elevation of 14,100ft. This mountain is famous for holding an annual race for both cars and motorcycles, known as the 'Race to the Clouds'. There are very few barriers along the edge of the road and we watched a YouTube of a car going over the edge (same corner as in the 4th photo below). Luckily the guy climbed out unscathed after rolling down quite a long way and completely destroying his car.
At the top there were frequent loud hailer messages advising people to travel down in a low gear and half way down there is a mandatory stop for cars to have their brakes checked to ensure they are not running too hot!
