Sounds like more testing is in order...Somewhat surprising a dealer has it absolutely 100% charged, you figure by the end of the test drive there would be enough of a drain to notice a difference...
Except to get "auto breaking" you need to change trims to the Premier and add an infotainment package...Also, unless I missed a news article, the point of it is a last resort/soften the blow functionality vs autonomous braking...Perhaps under certain conditions such as single digit speeds it could indeed prevent a collision, but it wasn't designed to be used as an ACC replacement...They got you covered... the auto breaking won't let you hit the car in front of you
I'm not going to test it like I tested the lane keeper (it worked perfectly by nudging the Bolt back into the lane), but I assume the auto breaking will work perfectly too.
