Human Factors
We were departing on the morning of a fly-in-breakfast. I was a Pilot Not Flying (PNF) as a right seat passenger. Pilot Flying (PF) was talking during taxi and not guarding radio. I heard a flight of two making pattern calls in the background. As we approached the hold short line; PF made radio call that he was taking the runway for departure. Aircraft Y on final called that he was on short final. PF stated that he would wait for him. Aircraft on final stated that he was flight of two and to wait for both. PF acknowledged he would wait for both. While flight of two was on roll out Aircraft Z called turning base. The PF then radioed he was taking [the runway] for departure and started to roll onto runway. He seemed unwilling to wait for traffic on base to land before his takeoff. As we crossed hold short line; I could see the Aircraft Y just starting to turn off. As we lined up on the runway; Aircraft A was still on roll out. PF was now caught between aircraft on final and aircraft on roll-out. PF stated 'We can make this' and throttled up to takeoff. We lifted off before aircraft on roll out and turned left to not overfly the aircraft. Factors contributing  to this runway incursion was PF lack of situational awareness and unwillingness to wait for proper separation with landing aircraft before starting takeoff.
The pilot of an RV-10 placed himself and his rated pilot passenger in a difficult situation when he elected to take the runway between landing traffic that had not yet cleared the runway; and traffic on final approach. The pilot was also observed to not utilize effective sterile cockpit practices.
