Yes, I'm sure that there are many people out there that believe that they are getting good economy by getting into top gear as soon as possible, irrespective of the speed that they are doing at the time. So they are into top gear by 30 mph, then trying to maintain that speed or accelerate with a heavy throttle opening and putting stress on the crank, rather than higher revs and a much lighter throttle opening.
You only have to ride a bike to see how much energy is used in both scenarios.
