Has cycling changed your driving habits?
I noticed that I tend to coast to a stop for a long distance if the light is red, rather than stay on the gas only to hit the brake 500 feet later, and no one else seems to do that. I sometimes stop past the stop line at a red light or stop sign if I'm first, since I'm used to stopping ahead of the traffic (my passengers think I might run the stop sign or light). I try not to accelerate on an uphill because I know that will use more energy than maintaining my speed or decelerating. I constantly put the AC on and off on hot days, putting the AC on when slowing down and putting it off when accelerating. On a road with a lot of traffic lights, I might prefer to cruise at 15-25 mph and get all the green lights than go 30 mph, stop, go 30, etc. One bad thing is that I might not stop in a crosswalk for a pedestrian on the opposite side, or I might creep up slowly to a crosswalk while a pedestrian is crossing it, rather than coming to a complete stop. On a bike, I would just go around the pedestrian in the crosswalk. And I treat bikes like royalty, giving them 5 feet or more, expecting them to run stop signs and red lights on the bottom of a hill. Sometimes I would follow a bike at 15 mph for over a mile on a narrow road where there's no space to pass safely because I know the cars behind me would pass unsafely if I passed the bike.
