Coyote, my kids are already telling me I'm driving like a little old lady
I've found that, when I'm on the freeway and it's relatively flat, 60 tends to be my maximum now (and for my area, that's definitely slow lane!) if I want to keep that mpg registering high. Down hills I find I'm not going much more than that- maybe 65. I passed a cop this morning, did my well-learned "yikes" as I stared at the speedometer and then laughed at myself.
