> It can't just be 2X or even 10X safer than humans if the manufacturer is liable for the accident. That would EXPLODE the cost of these cars and bankrupt companies -- even if just a small fraction of today's fatal accidents due to driver error became Google's liability.
If the owner/operator bears no liability and all liability is on the manufacturer, it transfers the liability cost onto the manufacturer, but even if it is as safe (not 2× or 10× as safe), that just means the manufacturer rolls the cost to (self-, likely) insure for that liability into the purchase price (but the purchaser doesn't need to get their own insurance, so the total cost of operation to the purchaser is unaffected.)
And, of course, if a company like Google is both the manufacturer and the owner/operator (e.g., using the vehicles in an Uber-like service tied in with Google Maps and Google Now, or using them for Google Express delivery vehicles with smaller robots onboard to deliver packages to the door, or using them for Google Street View camera vehicles, etc.), operator vs. manufacturer liability makes no difference.
