Need to create a traffic break it actually helped not hider traffic flow the traffic in front was traditional California stop and go and the traffic behind me was fast flow High volume. stop and go is hard on the gas and brakes.. would you rather go 65 mph then 45mph then 60mph then 40mph etc.... or go a steady 50mph? That means I saved( counting every single car behind me) 20 gallons or more of gas total . lower gas consumption = lower demand = lower prices for all IF every one would drive better the GAS price would be lower because of less demand for it.. I know every one complains about why their car is not getting great MPG etc.. and you Net timed saved would be 0 seconds 20-35% more gas used it's just like the people who speed from red light to red light YOU saved 0 seconds congratulations and wasted 30% more fuel..
