That road looks like Utah-12, which was scary and hilly enough in a car. I saw a decent number of people biking it, too. There’s some crazy ascents on that thing.
Who is GMC going for here exactly? “You know, I really love riding this lightweight racing bicycle, but I’d really rather be carrying it around in a bloated, fuel-guzzling, poorly-handling truck.”
For me, the impressive thing about that truck is the high front end, which would be very effective at knocking pedestrians and cyclists to the ground (the better to cripple them for life). That’s real power. Power like a pro.
