Levinson went further and specifically pointed to Tesla’s decision to rely solely on cameras to support its driver assistance system. “Our perspective is you really do need significantly more hardware than Tesla is putting in their vehicles to build a robotaxi that is not just as safe, but as especially safer than a human,” he said.

Levinson’s comments come just a few weeks after Musk revealed the prototype of Tesla’s so-called “Cybercab” robotaxi. Musk also announced at the Cybercab event that Tesla wants to start allowing Model 3 sedans and Model Y SUVs to operate as robotaxis in California and Texas by the end of 2025.
