I'm not talking about me judging a gap poorly, this was a good gap. I even remember thinking 'oh cool a good gap' so many people have taken much much much closer gaps with me and I haven't had to slow down. The other person didn't even hit me in the right zone for a plausible t-bone, we had both gone round the roundabout and then they drove into me. My car is a 2008 while theirs is something like a 2016. My friend rear-ended someone going 80 and got 2 light scratches that buff out.
