There _will be accidents_
""Well, when we have autonomous cars, there won't be any accidents," one Bosch employee said"
And that tells to the world that what is the level of expertise in this company: They are morons.
Autonomous car will crash, every one (model, not necessarily every car) of them.
Partially to "unseen environment", i.e. snow, gravel, flood, what ever. Or they just stop when there's 20cm of snow on the ground as they've no idea what to do.
Partially to programming errors: There're tens of millions of lines of code: There's no way there aren't any major bugs, causing accidents.
Then there are _mechanical failures_: Autonomous cars are still cars and _cars always fail_: Nothing in the world can stop that.
And finally: _Other_ autonomous cars by different manufacturers which react differently and cause accidents.
Most simple example: A British car in France would try to drive on right.
Ergo: Anyone claiming that there won't be accidents, is a patentable idiot.
