This past spring coming home had a car suddenly come to almost a full stop on the I75 from 60+ mph to let a car merge in from an on-ramp in heavy bumper to bumper traffic. Both the car on the I75 thru lane and the car on the on-ramp each kept slowing down more and more in a game opposite of chicken while I was sliding my trailer and front truck wheels trying to avoid slamming into the car in front of me as it quickly kept slowing to a stop.
AS for the OP good reminder to always drive defensively even if it means occasionally going backwards to maintain your safe stopping distance while towing as vehicles continually jump into the safe space you are trying to leave yourself.
