Last year, GM Cruise recorded 447,621 miles driver with its autonomous fleet. Of those miles driven, the company recorded just 86 disengagements that required human intervention. This averages out to about 5,200 miles driven between disengagements, which is a considerable improvement over 2017’s 1,230 miles driven between disengagements. While GM Cruise did improve, it’s not the best out there. Waymo, a main competitor from Alphabet (Google), logged approximately 11,000 miles between disengagements, according to The Detroit News.
