Nope, daily on the A55, got a few ups and downs but relatively flat. To be honest, thought about selling my car but love the reliabilityRegularly get about 300 miles on a motorway run from Ipswich to N Wales. Was the 475 miles, downhill from Scotland !!! 
As for rarely going over 60, why not save the money on insurance and buy yourself a Nissan Micra !!!!
