Missing from the article is the nature of the link to Mobileeye -- the Volvo cars Uber is using come with collision avoidance built-in, Uber disabled it. The Volvo collision avoidance uses technology from Aptiv, which in turn uses technology from MobilEye.

So this isn't just a random company saying "we could do better", this is the company with equipment already on the car (though disconnected) defending their reputation.
