The last few major runway incursions also included a lot of people stepping on each other at critical moments.

I was probably about 5 seconds from V1. That's about as long as it takes for the crew behind us to accept the takeoff clearance. Hopefully, the FO I'm with has the witts to wait for the aircraft behind us to finish their radio transmission before they inform the Tower we are rejecting. And hopefully, the crew behind us isn't too focused on their company's takeoff procedure/callouts to notice.
