Oh yes, the turtle was showing for several ks before getting back, on the equivalent of a b road, then a country lane for the last two. I was hyper-miling big time, on the 90kph stretches I was mainly doing 80 (a real faux pa that insensed a following lorry driver) but letting the car roll down hill where possible with zero regen, then on a long steep uphill I dropped to 60, where fortunately there was a crawler lane. On the country lane I was doing 20-30 as there was nobody following. I did not go fast enough to find the speed the car was limited to, but it will do at least 80kph on the speedo, i.e. 56mph.
