Momof1in150, your no-left-turns plan appeals to me. It makes me recall that I actually put a little extra mileage onto our car when I drive our friend home because I turn right and circle around to avoid turning left onto one of the busiest, most accident prone streets in the city. Then I encounter a one-way street and so have to drive a bit farther just to avoid that left turn.
Later, when I am out

for exercise, I will also stop at the grocery for a box of crackers: No miles racked up except on my shoe tread.
