I'm searching for a short label (preferably one word or a few short words) on a computer interface which simulates a traffic control. If a car is in front of a traffic light and the traffic light turns green, there is an option to delay the car for a few seconds so that it doesn't drive off immediately (to simulate the driver's reaction time).
It would be a nice and simple checkbox, but unfortunately in English the term "drive off" contains the word "off", which might confuse users:
[ ] delay driving off
It might also seem that checking this checkbox turns an option off. It's especially annoying because there are other checkboxes nearby which contain the word "off" for exactly this purpose: for example, "turn lights off after (some event)".
In other languages this interface is shown in, it's not a problem, because their translations of "driving off" don't contain the equivalent for "off".
My problem is that other synonyms don't unambiguously mean the same. Just "departure" seems forced, isn't it mostly for trains or buses leaving a station?
"delay driving away" might be a compromise, but I have never heard it in the context of a car driving off in an intersection after the lights turn green. Merely "starting" is not good, as the engines are already running, there is nothing to start.
