We're not discussing the definition of phantom braking here, the car braked unexpectedly & that should not happen. There are various causes, either shadows, lorries, road mapping or other & all have the same potential for disastrous consequences.I don't use AutoPilot other than on motorways. I do occasionally get the shrill beeps from the Forward Collision Warning, it's a bit jumpy. I'll value it the one time I'm not paying full attention some day.
So had the cars speed limit changed to the 30mph road underneath? A mapping error? I'm not sure if that's what's called Phantom Breaking. Also a dual carriageway rather than a motorway, maybe that makes a difference.
