Narrative:

Aircraft was cleared for takeoff on runway 26L. First officer was PF. After setting takeoff power, I looked up to see an airport vehicle exiting the south edge of runway 26L. The vehicle had crossed after we had been given a takeoff clearance. The vehicle crossed 6000 ft down the runway at a high rate of speed from right to left. The vehicle then remained clear of the runway for the remainder of the takeoff.
