Re: Sooo.... wait...
When I first read The Reg's report, I thought there had been some misunderstanding or that the NTSB had fumbled the wording. I read a few other reports which clarify the NTSB report slightly but confirm that the Uber had no automatic emergency braking system.
I can understand why Uber disabled the manufacturer's safety systems in the Volvo XC90. It wouldn't have been a good idea for the car to have two independent systems driving the car; it's not comparable to multiple linked systems which are used to fly aircraft. Everything else is inexplicable to me.
