NHTSA Complaint #11501477 — 2018 TESLA MODEL 3

Significant phantom braking issues on two lane highways like US95 in NV. The vision system cannot reliably tell if something is in the road or not when there clearly is nothing, cars or objects. Unclear if my 2018 if the radar is still active, but the vision software cheats I believe by using traffic in front to know the road is clear, but when there is no traffic on a rural highway, it panic stops from 70mph down to 45mph quickly before I can disengage Autopilot. No shadows over the road, no tree, no over passes. Happened several times going south on US95 south on a cloudy day and several times going north a few days later on a sunny day. At all times nothing in the road. It seemed to be more confused on slight rise and downhill, but occurred in even flat road sections. I think the AI has not been trained in non-traffic rural roads and unclear if the radar is still active.
