I hate the warning myself and I use the app the parent is from. I also suspect I am an outlier in not having an accident in 20 years.
It’s this obnoxious audio warning that tells me I had a hard breaking and it’s 9/10 because I stopped at a red light that I would not have made on yellow. And then it sends me tips and reminders about reducing hard breaking events and it’s annoying. I know they have done the analysis but it detects moderate hard breaking which is frustrating. One of those things that I am sure in net is positive but perhaps slices of the population it does not benefit.
The lights should be timed so that you don't have to do that if you are driving the posted speed, but I know that's not always true.
