The video that has always stuck with me is when he explained the science behind how motorcycles are hard to gauge their speed and distance and related it to how pigeons see. It showed me that a lot of why drivers have a tendency to pull out and cut off riders is more to do with not being aware that it can be very difficult to calculate the distance and speed of a motorcycle the same as we do with a car. With that knowledge as a rider I have actually changed my driving and really make sure I fully check both directions before pulling out. I also, as a rider, pay attention to side roads and driveways and always assume the car is going to pull out. I have never almost pulled in front of a rider but I can say I have many times avoided cars by riding defensively.
