You can turn it off.
I know because I turned an alert on for myself.
Set it at 150 KM/h because if they catch you going 50 over in Ontario it’s not pretty, and the highest speed limit here on most highways is 100 (there’s a few stretches of 110).
Just the other day my son tried getting into the trunk while my engine was running in my manual 5, couldn’t, but as soon as I engaged the parking brake there was no issue.
Maybe it’s because you had both the brake pushed and the parking brake on, suggesting to the safety programming...
I consider this a safety issue as it could lead to being rear-ended if you accidentally stall while someone is following too close behind you: e.g., while about to make a left-hand turn at an intersection.
