I don't roll through stops or anything (I don't on my bike, either), but I definitely have to catch myself from yelling out "car back" when driving with my husband. Just today, we were carpooling in to work together and I yelled "clear" as we were backing out onto our road!

Oh, I also find myself getting annoyed with cars that slow as I follow them down a hill....like "come on...there's an uphill up ahead - don't lose momentum!"

When I first got my Prius, I was intentionally driving it like I rode a bike. Drafting behind big SUV's (even at a safe distance) made a real difference in mpg, so used my knowledge of how to conserve energy on a bike on a long ride to get better mileage on my car! (coasting down hills, using momentum to get up hills, slowing but not completely stopping at turns, drafting behind vehicles or staying in traffic instead of pulling into the left lane to pass when on a highway, etc).
