The 145-mile jaunt between Flagstaff, Arizona, and Phoenix is almost entirely downhill. With a drop of approximately 5,800 feet between the two cities, the road that joins them -- Interstate 17 -- has multiple warnings about saving your brakes (meant mostly for big rigs) and is peppered with sharper twists and turns than your typical highway. Yet, while I was behind the wheel, I did almost nothing for the entire drive thanks to Cadillac's new Super Cruise feature on the 2018 CT6.
