I do the same but when in traffic, there are always those jerks that cut in front to fill the gap or rushing up to my rear while slowing to take a corner. Guess if I have to wait longer then so be it.Since getting app and being able to see my score 2 days ago, I was being dinged for following too close. All other areas were ok. I have found a gap of about 3 seconds appears to be the sweet spot. I am literally counting from landmarks "thousand one, thousand two, thousand three..." No dings since starting this and my average us coming down.
