Small update - we decided to take Hermann for our trip down South (all the way to the south coast of England) as Mrs A's
new car is almost too new to take on such a long trip.
Hermann likes these longer journeys both are well above the govt. average. We didn't drive in eco mode for them either, mostly set a cruise for 70 (the limit here) and relaxed.
Expect the average to drop again now that he is back in Edinburgh and the carp traffic here.
