“A four-wheel-drive vehicle is required beyond the 9,200 foot level as the air is too thin to adequately cool a vehicle’s brakes upon descent… “Most car rental companies void the rental contract if their cars are driven on Saddle Road and to the summit… “Temperatures on the summit can fall to 20 (F) ( -4 (C)) within a matter of hours; it is highly recommended that all visitors to the summit take warm clothing and sturdy footgear sufficient to withstand the elements should the vehicle break down…” And of course: “…Winds can reach 150 mph; beyond 75 mph vehicles are at risk for being blown off the road. Caution is advised.”
Makes me want to visit, actually. But perhaps in someone else’s vehicle.
