And imagine if the cruise gets it wrong!
yeah, a primary concern! Of course, as with the steering wheel, brake pedal, and every other control at your disposal - its ultimately up to the driver to responsibly use their car's features correctly. That's easy to say here

But I'd like to believe that the driver would be alert and not depending on the active cruise control to
get it right! Just like a GPS that tells someone to turn right into a wall... is the GPS at fault? Certainly the wall isn't. That leaves the driver.
