It happens to me every once in a while, I get in the car after a hike or pickleball or whatever, and totally forget to stop my activity. Then I have to go in to connect, and edit the activity based on the speed or guess what time I stopped.
That works ok, but it seems like garmin could easily detect in software when I'm driving based on my heart rate and speed. It would be nice if there was an option in garmin connect to trim driving, and another spot that would be cool is on the watch. There could be an option when I stop the activity to "Save and trim driving". Or even better yet, the watch could detect that I'm suddenly moving at inhuman speeds during my activity and alert me and ask "Would you like to stop the activity?"
