I agree, but you actually can slow down relatively quickly at stop-and-go speeds if you have some RPM on a big V8 and you take your foot off the gas. Certainly I try to remember that, because I tend to avoid using the brake pedal except when strictly necessary. I've seen some people behind me act kinda surprised that I can slow down without activating the lights. Yes they should be watching my car, not my lights, but this is the real world.
