In the video below, the Driver had both a motile phone on the HUD and had placed ground markers along the runway!!

Interesting you mention ground markers. Isn't just plain maths your friend here. Calculate the optimum acceleration at a given throttle setting. Factor in a margin of error and then put a post beside the runway that means "Cut engines" and you should be fine.
Of course, what happens if the engines don't cut. Can you have a runaway at max power?
