Teslas work exactly like this without Autopilot. It's one of the assistance features, just like warning if someone stops in front of you and you don't seem to be reacting. These features also get better as Autopilot gets improved with less of the nasty edge cases. So even if you don't trust Autopilot, Tesla's improvement of the system over time is still useful in improving those other assistance features.
