Don't just watch the lite coming up-look further down the road to the 2nd or 3 rd visable lite------get used to how long they are red/green------don't gas it hard to get thru as it changes---------if lite has been green quite a while you can back off a little early to coast further plus you'll be at the front of line for choices at the next segment-------

In aviation there is a speed rate known as "best rate of climb", or the speed that will get you the altitude your climbing to(CRUIZE) in the least amount of time-everybody knows that cruise power is more effient than climb power----------BUT----at a higher speed during climb will take you longer to get to that more effient speed--------you get a lot further down the route with less fuel used and in less time IF you climb at a higher rate of speed--------

Getting to that most effient speed sooner helps, but in the long run your brake wear will be one of the better indicators of your driving efficienty-----
