Auto manufacturers are rushing to be the first to sell cars that are semi-autonomous. But they have failed to invest in adequate training for sales personnel who can explain the features — and their limitations.

So what can go wrong?  Here’s one example: According to a recent report in Automotive News,  “As Donna Lee approached the intersection of Roberts Drive and Spalding Drive in Sandy Springs, Ga., the salesman in the passenger seat told her not to hit the brakes, even though two cars were stopped and waiting at the red light ahead.

According to court documents, Lee and Mercedes salesman Desmond Domingo have similar accounts of what happened next on the evening of May 10, 2014. The Distronic semiautonomous system in the Mercedes-Benz GL450, which Domingo believed would bring the car to a full stop, did not kick in as he expected. The Mercedes slammed into the car in front of it at around 40 mph, causing a chain reaction of crashes that left a 16-year-old driver with a concussion and significant damage to the cars involved.”

CARS has testified at forums regarding autonomous vehicles that they should not be offered for sale to the public until they are fully autonomous, and they have been proven safe through at least one year of real-life testing in all normal weather conditions, including heavy rain, fog, and snow. Otherwise, consumers who purchase the cars may end up stranded, or in collisions — particularly if they purchase the cars as used vehicles, and are not familiar with their limitations.
