Incompetent driver on board, apparently.

Road safety regulators said that some of the crashes “involved collisions with clearly visible objects that a competent driver would be expected to avoid.” […] It’s at least the third time in the past year that Waymo has recalled robotaxis over potential software issues. In February, the company recalled 444 automated vehicles after two robotaxis crashed into the same truck that was being towed, according to The New York Post. Last June, 700 robotaxis were recalled after one crashed into a telephone pole in Phoenix.

Jake Glaser posted this Waymo struggle example in Los Angeles to Swastika:

Waymo turned into oncoming traffic on the way to work. It sat there confused for 45 seconds with its hazards on. Then it proceeded to back up into oncoming traffic. And they’re about to let these guys on the freeway 😂
