I've driven to the top of Pikes Peak twice in rental cars while on a business trip to COS. All I can say, these guys that race the PEAK are crazy. I was feeling the affects of lack of oxygen at the 10K foot mark and by 12K I had all the classic signs of hypoxia and at the summit we got out of the car to take a photo and I was hardly able to talk. Not to mention the many places the road just falls off into nothing.
Scary, but as they say, racing is racing so have fun and be safe.
Best EV Range 50.x miles (more than once)
