Anyone notice that Tesla's web site no longer claims Blind Spot Detection or Lane Departure Warning as a feature. Advertising was prominent in describing their autopilot and was in their press releases, but now the site is mum on these features. Tesla marketing 101: overpromise to pump up sales, underdeveliver even with software updates and then erase the evidence or the original promise. It was some crafty computer science for sure to take the short-range ultrasonic parking sensors and reformulate them as a blind spot detection feature, but reality has set in. As many threads here set forth, their AP 1.0 sensors were incapable of making this work even with software upgrades and some are saying the same for their AP 2.0 sensor suite. AP 1.0 is just lane keeping with adaptive cruise control as a practical matter. It remains to be seen what AP 2.0 will reliably support. Too bad for all buyers that were beguiled into purchasing because of those advertised features. I fear the L5 autonomy is going to take the same trajectory.
