I have a friend who was told this 30 years ago so as a consequence has never driven above 56mph. Swears it makes a huge difference to his consumption.I seem to remember that the optimal speed for fuel efficiency for an ICE car was on average 56mph with consumption increasing surprisingly rapidly once over. I have not seen similar for EV's, does anyone have info on this?
Personally I could not tolerate being constantly overtaken by all other road users.
