On my last trip to Mt. Lemmon, one on the local guardians of Truth, Justice, and The American Way was kind enough to take some time out of his busy day to explain just how many bicycles. cars and motorcycles go up and down the mountains on the weekends, and that he wearied of med-evac'ing their operators to the local hospitals. He indicated that weekends would call for a more relaxed pace, and that perhaps it would be better to moderate my pace enjoy the scenery rather that the pavement design. Since he was kind enough to offer this advice without charge, I decided right then that my next visit would be on a weekday.
Considering how many bicycles that were in your video, I think that I made the right decision.
