Wick. Couldn't agree more! I try to do this with my cars now and then too. See how steep a grade you must go down to accelerate in neutral. . And what's the holdup, cause it's costing me gas mileage! Damn disc brakes, never fully disengage!

15sec...1 min...2 min? Now spin the other wheel. Whats the difference in the times?
If you only get 15-30 sec then your using up engine HP to move the car. Get the wheel to spin for 1-2 min. and you will feel the difference. Same thing with tires.
Take your Bicycle and set the air pressure at 15psi and ride it...now up the tire pressure to 40psi and go for a ride...feel the difference? I could take a Kart and give it a push in the garage and it might roll 3ft....remove as much friction as possible and push the kart....across the floor and out the door she would go!
I hope this information is usefull.
