limmortal 55mph on the motorway must have been a tough challenge not to let that right foot get heavy
You wouldn't believe - i was trying to hold back a paving slab by the end of it.
its not so bad if you got the cruise contol on and your in no rush.... you can actually get some decent MPG with the AGP doing 60 on a motorway.

Right foot will always get better economy than the computer - if you anticipate the hills and drops you can judge your speed on approach to maximise!yea but motorway driving is BORING!!!

to be honest i thought id never use it but after i came back from america, where i notched up a silly amount of miles on the "highway" i got used to it.
odviously im sure the cruise control will have an effect on your MPG but how much will it be? cant be a lot really?
