#NavigateOnAutopilot

In this writer’s opinion, one of the greatest things to happen to high-speed motoring is the blind spot monitoring system. Try as we might to religiously check our mirrors and peer over our shoulders before each lane change, there’ll always be that time we half-ass it, just as an unseen car creeps up in the shadow of our B- or C-pillar. BSM can be a savior.

However, handing over the entire lane-change process to a combination of software and sensors, at least in Tesla vehicles, is far, far worse than doing it yourself, Consumer Reports claims. After giving the latest update to Tesla’s “Navigate on Autopilot” feature a shakedown cruise on the highways of Connecticut, the consumer advocacy group handed the system a failing grade.
