Although universaly hated i drive a lorry mainly around London and the amout of friendly car drivers that take 1 look at you coming down the road and think "oh i aint getting stuck behind that im pulling out" ! Im sure if they knew how long it takes to break in a 30-40 + tonne lorry and the mess it makes against there 1-2 tonne car im sure they would re-asses the situation ! Im no expert driver or rider at all but some of the driving of anything on wheels i see on a daily basis is wose than poor.
I agree with you there, I used to drive Hi-Hab's, plus they have no understanding of the wasted energy it costs getting back up to speed again, something a cyclist will understand a little about, especially in the early days when things are so difficult.
This is way you are taught to read well ahead and anticipate ease off well in advance cover the brake and hopefully you will avoid the need to brake, because as soon as you touch that brake it wastes energy, thats not to say dont use your brakes, of the Daf 65's in the company I worked for I had the highest avg mpg, something approaching 14 mpg, the others were getting something like 12, i know other variables as well, but I think it does show what a difference it makes, thats like 16% more miles, I see it with the way our lass drives too, she could save some money instead of moaning about the cost, but theres no telling some folk, at least shes a safe driver.
