Sure, but aren't they already if you look at the accident per total miles driven ratio?
Of course, there will be accidents and people will die. People die every day in car accidents.
The human driver fatality rate is roughly 1 per 100M miles. There has been 1 fatality with less than 20M self-driving miles across all companies. So, if you group all the companies together, they are still more dangerous than human drivers.
But frankly, I think grouping Uber together with more responsible companies does the whole industry a disservice.
