What, Tesla still can't detect big, obvious obstacles reliably? That's pathetic. A half-dozen cases of running into stationary obstacles at full speed should have taught them something.
Running into obstacles at full speed, with no braking, is quite rare for human drivers. Usually, there's braking, but too late. Mercedes once did a study showing that over half of accidents would not have occurred if braking started about 100ms earlier.
Tesla's approach means the driver has nothing to do until something goes wrong. Then they have to react in under a second. That just doesn't work. That's been known for decades.
Great video on cockpit automation: "Children of the Magenta" (1997).[1] It's an American Airlines chief pilot talking to his pilots about automation-induced accidents. The aviation industry started dealing with over-reliance on imperfect automation a long time ago.
