I hate this feature. It deployed on my Grand Cherokee once while I was attempting to pass (in a passing lane) on a two-lane highway. I still don't know whether it was an oncoming vehicle or a vehicle I was attempting to pass that set it off, but when you have your foot firmly on the floor of a Hemi GC, the last thing you expect is for the vehicle to decide on its own to hit the brakes. Fortunately, there is a switch on the center stack to turn it off, and it stays off until you turn it back on.
I have heard too many horror stories about automatic braking to consider your experience a Giulia-only problem.
Everyone here should also understand that so-called consumer protection groups like the Center for Auto Safety and Public Citizen are demanding that the NHTSA require these systems on all new vehicles, and in fact the automakers have agreed to do so beginning in 2022. This means that we all have to pay - both literally and figuratively - for the sins of people who can't seem to focus on driving while behind the wheel. Hopefully they've perfected the technology by then.
