Regarding long distance driving, I've just done Sheffield to Lisbon, via Santander ferry, using Eco mode all the way, and I found the driving very relaxing. The northern Spain and northern Portugal mways are so free of traffic that you can use cruise control all the way. And on the crowded uk mways, with their speed limitation, you just sit back and let the system work out how to use the drive. For the record, Sheffield to Plymouth, 55.7 mpg, Santander to Lisbon and return, 48 mpg (very hilly terrain), and Plymouth to Sheffield 49.6 mpg. Just relax and enjoy the scenery :-)
