At the very least they couldn't they detect imminent collisions with pedestrians? walls?

My non-Tesla has a radar for cruise control and imminant crash detection — while annoying at first, it is unfailable. As I've aged (¡perfect driving record!) my thought process has gone from more horsepower! to more safety!. Now when my car beeps at me I'm more-inclined to listen cautiously.
- bryanlarsen 1y agoNot really. Stopping distance at 20mph is 20ft on dry pavement, and it goes up quadratically the faster you're going.
- Kirby64 1y agoUltrasonic isn’t particularly useful for fast reactions. If it’s navigating around a parking lot slowly, sure, but if you’re going any reasonable speed it’s basically useless.
