Tesla Autopilot most often used between 55 mph-65 mph, MIT researchers say

The tech is pretty cool, but don't let new developments in partially self-driving cars distract you from your responsibilities behind the wheel. A Tesla that the driver said was in Autopilot mode struck a parked police vehicle in Laguna Beach, Calif. SAN FRANCISCO -- Tesla's innovative and controversial Autopilot software -- which powers the partially self-driving features of its electric cars -- is most often used for highway driving, according to the initial findings of an MIT study using volunteer owners. The research, shared at a conference in Cambridge, Mass. Wednesday, came a day after the latest crash of a Tesla using Autopilot, and as two consumer groups renewed criticism of the software's name and marketing, which they say dangerously misleads drivers.
