Bit of a pedantic one here (when are my threads not? ) I'm not sure how exactly to explain this clearly, so i'll give an example instead: You, the driver, have just accelerated up to a 20mph limit and have activated the speed set and are in Notch 3 or 4 of power. The speed limit has just increased to a higher speed limit and you can now accelerate up to this speed In this scenario, are drivers trained to: A. Disable the speed set and start off accelerating in Notch 3 or 4 of power. B. Reduce power first to a lower notch, then disable the speed set and build the power back up again. If anyone could shed some light on this topic i would be very grateful!
