I use speed limit markers for my tests. I come to 45 MPH as I approach a "Speed Limit 45" sign, then let off the gas as my front end comes alongside it. (Shifting to neutral has no effect, since this is an auto trans- I've tested it, and the RPMs don't move, nor does the car. This is at speed, though. I don't measure the coasts to a stop, since I'm on a public road. Obviously, the car crawls on its own power from a stop.) Then I look at my speed as I come to the "Speed Limit 35" sign, and the subsequent signs. Before, I'd hit 35 as I came to the 35 sign, but now I'm going 40 as I pass it, and don't reach 35 until I get to the city limit sign. This is on the road going into my town. Two lanes, level road.
