An interesting read that pretty much nails it...

again....
it's an interesting read, but it's b/s in regard to "actual distances travelled"..
I have to dig to find one of the dozen times I posted actual distance travelled, along a path, located 4 ft on either side of the centerline of a curve. Unless all you do is ride in the city, with a 25 ft radius to the centerline, the percentages of distance travelled are less than 15%
Does not compute when we are seeing full tread on right side and no tread on left side....
most folks read that sites drivel, and believe it, without ever picking up a calculator, making a sketch, and comparing various radii turns / curves... based on actually being in the center of each adjacent lane.
If they did, they also would be calling b/s on the left vs right turn thing.
jmho. ymmv
ex:
90 degree turn,
25 ft center, right turn 21 ft r. (33' dt), left turn 29 ft r. (45.6'dt) =28% diff.
60ft center r., right turn 56' r. (88'dt), left turn 64' r. (100.5'dt) = 14% diff
100 ft center r., right turn 96' r. ( 150.8'dt), left turn 104' r. (163.4'dt) = 8% diff.....
anything over 100ft radii is moot.
and you ain't going around a 25' rad. at 50 mph
