I use it a lot. I set it 10kmph above the speed limit as well. It’s not perfect in a lot of city conditions and it can behave unexpectedly as well in these condition. Unless I want to fiddle with a spacing distance all the time and avoid sudden breaking for no reason I have to use it sparingly depending on time of day and location. Outside of cities it tends to work quite well for the most part. Some sharper bends trigger breaks too soon for no reason as well even though I’ve set sensitivity to the lowest.
Also during heavy rain it just tends to ignore everything in front of me and starts accelerating to the max set speed.
That’s why I always only upload pictures of other people
