The constraints on autonomous public transport systems make them viable. You create a safer system that way. Additionally, you prevent unnecessary work getting multiple vehicles to the same location roughly at the same timeframe.

I understand people want a faster solution! But mixing autonomous vehicles with human drivers isn't the way.

Moreover, these companies commit statistical fallacies discussing safety. Human drivers have driven more, as the article suggests, and in a myriad of environments. Many variables are at play, and it's disingenuous to compare this way.
