Pilot reported a truck drove directly in front of his aircraft and required him to brake suddenly.

Narrative:

Completed a training flight with my son and was taxiing back to the aircraft's hangar along a designated taxiway. Approximately 300 feet from our intended hangar; we noticed an FBO operator in his personal truck backing toward and then parallel to our taxiway aiming south then stopping to our left. It appeared he saw us so we continued our taxi. As our distance closed to within about 50 feet; he proceed to start driving again and then executed a 180 turn to the right; across the taxiway; cutting across our path and causing us to rapidly apply brakes to avoid a collision. We stopped approximately 25 feet from him. As he drove passed us he looked directly at us not seeming to care we were there; and drove away. After he was fully clear of us; we continued our taxi. Weather was not a factor and the area was adequately lit. Time of occurrence was xa:08 local time and sunset was xa:13 local. A witness came to us afterwards expressing his anger toward this persons continuing disregard for safety. On numerous occasions I have witnessed him throwing a ball across this same taxiway to exercise his dog. I've also watched his [relative] use a drone to run his dog across the same taxiway. What I believe caused this conflict is this person continuing disregard for safety. The only thing I feel I can do to prevent this from happening again is to find another place to store my aircraft.
