I know some really bad drivers that have almost no 'accidents', but have caused/nearly caused many. The cut off others, get confused in traffic and make wrong decisions etc...
Waymos, by media attention at least, have a habit of confusion and other behaviour that is highly undesired (one example going around a roundabout constantly) but that doesn't qualify as a 'crash'.
Well, yeah? Or rather, if it's not, then I think the burden of proof is on the person making that argument.
Even taking your complaints at their maximum impact: would you rather be delayed by a thousand confused robots or run over by one certain human?
Depending on the relative rates and costs of each type of mishap it could go either way. There is a crossover point somewhere.
The fact that you're coming right out the gate with a false dichotomy and appeal to emotion on top tells me that deep down you know this.
