🚧 THIS IS A TICKET MIGRATED FROM UPVOTY. The original ticket and comments will be available for a limited time over at:

———————————————————————————
Allow reference consumption to be specified at speeds other than 65mph / 110kmph - I have a “towing” configuration, it is illegal to tow above 60mph!!

I know my towing consumption @ 60mph - I can’t work it out (legally
) for 65mph…
