On today’s brain-addled episode of Quick Charge, President Trump says electric car drivers have a disease, Full Self Driving won’t stop earning Tesla drivers tickets, and Waymo’s CEO spends over forty minutes explaining why Tesla’s tech won’t ever beat a human driver.

Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can’t take a self-driving system to full autonomy, arguing that “weak sensing” hits a safety ceiling long before it reaches superhuman performance.

He never said the word Tesla. But camera-only is Tesla’s entire bet, and this was a direct shot at it.
