As I released the brakes to start my roll forward I saw an airplane taxiing at high speed past me on the right and then in front of me onto the runway. There is no way he could have not seen me. He had to taxi forward of my position and around me in a very tight area to avoid striking my wingtip or going off of the narrow 40-foot-wide runway.
