When people wail about Pikes Peak being paved, I always point them to this video:

Things might change, but then they always do.
For those paranoid about excessive speed, the altitude will suck that dry.
If you ever go, don't make the mistake I did and chug down Coca Cola at 12500 feet. At that altitude the C02 gas expanded in my stomach quite radically and I had it coming out both ends in spectacular style. Thank god for a good friend to help me out and a portopotty otherwise it would have been quite the crowd pleaser. Or not.
Anyways it is definitely worth going at least once in your life.
