There should really be an automatic short emergency delay on the governor (say 30 seconds) that would allow for just such a situation. Certainly the tires wouldn't overheat in that short a period, if that's the real concern.The max speed governor on my car's engine works only when I am passing a slower vehicle on a 2-lane road and a big truck is coming towards me.
They say it is for tire safety. Maybe I should slow down.
