Cruise severely botched an accident investigation which they might have been cleared of if they didn't try to hide evidence from CA regulators [0].

Follow the laws and it's fairly easy to operate.

I was a happy customer of Cruise's btw and they largely solved the self driving taxi problem at the city level at least, but Waymo does have access to better mapping because of Google.

From the outside, with no insider information, my impression is waymo was under a lot LESS pressure compared to others to exaggerate their successes. This is just my impression but to me it feels like waymo was able to do a lot better self-policing or was much better at marketing to appear keeping safety at a top priority. For example, I remember reading articles that said the equipment on early prototypes were multiple times the cost of the Toyota Prius cars they were mounted on. Things like this make me feel safer with a waymo.

The real answer though is money. Since none of these investments are close to breaking even, the only obvious answer as to why one succeeds vs fails is the continued additional investment of money.

Execution, having a good idea and lots of money doesn’t guarantee success.

Waymo is 4 years older than Cruise
