Tesla Autopilot doesn't see stationary objects. It sees moving objects with its radar, and tries to avoid hitting them. It sees lane markings with its camera, and it tries to stay between them. Sometimes lane markings are confusing, worn, or inconsistent. If that happens, your Tesla will smash you at 70mph into a concrete barrier/police car. It will not slow down if it is uncertain about the lane markings, it will not beep if there is a stationary object ahead.
