Re: the W cross section.
The ecoline is different and probably better than the racing line or cutting the corner for FE given the rut tracks in the road. We are generally much slower than the road can handle. I think it is better to stay in your own lane and bank within the lane on the "W". Crowd to the right of the lane on a left curve and crowd to the left of the lane on a right curve. This is opposite of intuitively cutting the corner which causes negative banking from the "W" and crossing lanes can cause the car to dance a bit and require more steering input and scrub off speed.
I am sure this should be posted in a hypermile thread instead of here. sorry
Does anyone have an opinion of whether P&G would be effective at all with an automatic transmission and not doing neutral coast or EOC? I know this may be very vehicle dependent.
