The Bikers perspective of the Cage vs Bike

Motorcyclist:

Riding down a curvy road on your completely stock motorcycle you enjoy the fresh spring air in your face. The bike is running beautiful. The roads are clear, and you’re looking forward to a fun day out in the country. While doing the speed limit you notice a truck in a parking lot ahead getting ready to pull out. You prepare for an emergency stop, although you may not need it. Against all common sense, the truck did end up pulling out in front of you. You fortunately were being able to avoid hitting him. Oddly the truck does not accelerate after pulling out. You decide to pass a mile later. You flash, then proceed with a safe pass. While passing the truck, he begins to merge into you and match your speed. Survival takes over and you downshift and out accelerate the truck. The driver must take offense to being passed and decides to chase you. You both are exceeding the speed limit, though you quickly bank onto a side road and the pursuing truck can’t make the corner going into a ditch. You wait to see if they are ok, they get out and start running towards you. You take off. Going home, you manage to almost get run over a few more times but fortunately not chased again. What are wrong with drivers? You do nothing wrong, exercise all precautions and still enrage them. Why?
