50F, raining.

I had this happen this morning, Car A was getting tailgated by Car B. Car A turned right exactly in front of me to enter driveway but screeched to a halt across both the bike lane and the travel lane when freaked out by Truck T pulling out of the driveway. Car B had the left lane open but was tailgating A, anyway it also screeched to a halt, actually leaving enough room for me to go around A and in front of T which had never moved during any of this.

I might have also screeched to a halt in the triangle between A and B but with the rain my brakes were not screeching.
