What happens when Driver X stops pushing you around Daytona for the last few laps because his friend tells him he's winning the other race but is running slightly behind on time?
(Hypothetical phone call between Droptop2001gt and ACDCROCKS123 during the end-stage of a split-race decided by best overall time)
"Hey, AC, I'm leading my race, and crossing the start/finish line with three laps to go, with 42 minutes and 12 seconds on the clock. M-Stall is pushing and we are good to go to the end. Where are you?"
"I'm a lap down, but I'm pushing RFLX. He's leading. There are three laps to go, and we're crossing the start-finish line at 42 minutes and 8 seconds."
"Crap, we're four seconds behind you guys. Is there anyone else nearby to help him other than you?"
"No, it's just us."
"Can you stop pushing him so I can make up time on him?"
"Yeah, sure."
Now I can pass RFLX in elapsed time, without ever passing him on the same track, and there's nothing he can do about it.
