Some auto safety systems can be downright scary

Cadillac’s Super Cruise, a truly impressive hands-off highway driving system, got confused and lurched to the left and back again when it couldn’t find the lane markings as I began to drive across a bridge.

When I was driving Volkswagen’s 2019 Jetta it veered toward the center median when it detected what it thought was an obstacle. It was just a puddle of orange paint spilled by a road crew.

IIHS says a Tesla Model 3 often slowed down unexpectedly when it encountered tree shadows on the road, oncoming vehicles in another lane or crossing traffic far ahead.
