Happens to me all the time as well, I've got FSD (not the beta, the highway version, because apparently I take turns too quickly) and I have to be alert to bury the accelerator in case this happens on the highway. It's rare enough that I'm never quite prepared, but frequent enough that I know to be on my toes. I've never seen it happen when I was following someone, I bet the software is biased to follow the vehicle in front even if one of these events happen. It happens to me when I'm headed up a hill and there is an overpass on the far side of the hill, or I'm passing a low overhead sign. I can understand why radar thinks it's about to slam into a wall, from the radar's low slung perspective I'm sure it just sees a barrier ahead. Considering Tesla's early penchant for driving right into the side of a truck, I do somewhat prefer the sudden braking.
