Fucked up and overestimated the space I had to come to a stop and bumped into the car in front of me at less than 5 MPH. We both stopped, got out of our cars, checked for damage (there was absolutely none on either car, other driver even pointed out an old crack in a tail light and told me it was already there as reassurance). I asked if they were okay and they confirmed, we both got back into our cars without exchanging any info, neither personal nor insurance, and drove away. I am now sort of freaking out and am worried of potential future comeuppance. Any advice/words of wisdom?
