Lift if the other lane breaks?

No rule on the run it out other than maybe the safety of the other car/driver. If the car broke and was still up the track in their lane, etc. If they are at the line, run however you like. EWliminations, keep inmind, if they don't redlight him to let you loose, you can't break out. If they are staged don't redlight yourself or breakout.

Courtesy staging is common. Some cars need a bit of time to get from pre stage to stage. If you double bulb them, the timer starts and will redlight them if they aren't staged after 8 seconds, IIRC. That's the only deal with courtesy staging.
