Definitely this has nothing at all to do with highway speeds. We’re talking parking lots mainly. I don’t see the need for intuition. What’s the stopping distance at 3mph? Less than 1 foot with full pre-charged braking I’m sure. An effective system should be able to see a pedestrian 6-12” from the car in the direction of travel, and stop on a dime. At these speeds a false positive isn’t itself a safety risk, although of course you would seek to minimize them. It goes without saying the system will not be perfect. Neither are noise makers. I see no reason why such a system couldn’t be made that is more effective than fake engine noise.
