I have a 2020' Touring and trying to understand if the car is supposed to stop me or at the very least alert me when I'm inching up on an obstacle. For example when I'm pulling up to my garage door, there is absolutely nothing coming from the car. I've come as close as a foot away (at low speed) without the car complaining. I tried the same thing in a parking lot against a high curb or even a car that was parked in front of me. My Golf has basic sonar sensors up front and it beeps at me if I'm getting closer to anything in front of me. What am I missing here?
