The UK-based Institution of Mechanical Engineers makes the claim that self-driving cars could prevent 95% of all accidents.
That report seems to be based on the fact that 95% of all accidents are caused by driver error.
Claiming that self-driving cars could prevent all of these accidents seems like a stretch, and certainly the computer drivers will create accidents of their own making.
And it’s possible that self-driving car accidents could be more rare but also more brutal, particularly if autonomous vehicles are able to routinely travel at higher speeds than human drivers.
But even withstanding all of that, it’s clear why auto insurers are nervous.
