Narrative: I approach the airport ZZZ; received the AWOS (Automated Weather Observing System) winds (320/20 G26) and planned a RWY 29 left downwind entry for RWY 29.  Followed by a radio call. Since the winds were strong and gusty; I planned on a low approach over the RWY to determine the winds effects on the aircraft; made another radio call; downwind; turning base and turning final. I setup for my next pass for landing with the same radio calls.  I heard other aircraft radio calls from A/C (Aircraft) at near by airports. After a full stop; I taxied back to RWY 29 for more pattern work. I made radio call taking off RWY 29. As I added power and reach tail up speed I saw vehicle head lights on the RWY heading toward me.  I decided to continue the takeoff because a tail up abort with the gusty winds was risky and I determine I could get airborne before impacting the truck.  I pulled up early to get airborne to avoid the truck as I pulled up I was slow and the P-factor and the wind from the right caused the aircraft to drift to the left over the left edge of the runway and the truck.  I passed over the truck about 10 - 15 feet as the truck pulled off the runway on to the taxiway.  I made a radio call 'are you on the frequency' no answer.  I made three more touch and goes then a full stop.  As I taxied off the runway I saw a city truck approaching; I stopped in front of the truck and shutdown.  I exited the aircraft and had to reposition the aircraft into the wind and had to hold the aircraft from moving.  I called to the driver twice to get out of the truck while holding the aircraft.  Then he drove off.  I discussed the incursion with the Airport Manager. She stated it my fault because I heard the city truck radio call and I continued the takeoff 'to make a point'.  She also insisted this was not a runway incursion incident.  The Airport Manager titled was assigned to an administrative assistant who has no aviation experience.
