I have not heard of any road-legal EVs in any markets not having mechanical brakes. So either there was a failure of that braking system here or the driver was very confused about what was going on. The bit about the car still trying to move after the police had forced it to stop definitely raises this above the usual unintended-acceleration story, I hope there's a public report on what happened with this at some point.
