The saga of the fatal Tesla crash has taken another twist. Tesla has severed its relationship with Mobileye, the company that provided its semi-autonomous driver assist software. But Mobileye isn’t happy to take the blame for the problems. As reported by Reuters, the company is suggesting that Tesla over-sold the abilities of the car:

“It is not designed to cover all possible crash situations in a safe manner,” Amnon Shashua, who is also chief technology officer at the Israel-based maker of collision detection and driver assistance systems, told Reuters.

“No matter how you spin it, (Autopilot) is not designed for that. It is a driver assistance system and not a driverless system,” he said in an interview.

The company has also issued a press release.

More evidence, if it was needed, that this middle ground between human drivers and fully autonomous vehicles might be the most dangerous stage of the transition. Tesla is a company that thrives on pushing boundaries. Perhaps it pushed too far in this case, or perhaps drivers are too willing to give up control to systems not designed to drive unaided just yet.

Hoeverre, this very public spat between the two companies is doing nothing to inspire public trust in the technologies on offer.
