So it turns out that I have a problem with people who overuse their brakes while driving.  [I know, I know.  Am I happy with anything?]  I don't see the point in slowing down if there's really no reason to slow down other than to obey the speed limit, especially when gravity will cause you to slow down anyway.  For example, there's a hill on Route 10 near Ledgewood that's pretty steep.  The speed limit is 50 mph.  Coasting down the hill usually brings me to about 65 mph.  At the bottom of the hill, the car begins to slow back down to normal speed.  Yet people insist on wasting their brakes by maintaining a steady 50 mph all the way down the hill.  Here's my justification for not braking:  by not applying my brakes, I'm saving brake fluid and other related car parts.  In addition, I'm saving some ever-increasingly-expensive gasoline by eliminating the need to accelerate once I've reached the bottom of the hill.  By using the speed gained from going down that hill, I can coast for miles.  Think of how much gas could be saved by using energy generated by momentum.  Uh oh...random math proof:  let's say I can coast for a solid (1) mile with the momentum gained from coasting down the hill.  Let's say my car gets 25 miles per gallon.  Let's also assume that my car uses no gas when coasting (this is obviously not true, but it is true for hybrid cars).  So if I coast for that 1 mile without using the gas pedal, I will have saved 1/25 (0.04) gallons of gas.  Let's assume gas is $2 per gallon.  That's a savings of $0.08.  Not too much.  Now apply that to rush hour traffic.  Let's say 100 cars do this exact thing.  That's a savings of 4 gallons of gas, which amounts to $8.  To make it even more realistic, let's say that 500 cars do this exact thing every day for 1 month.  That's 500 cars x 30 days x 0.04 gallons, which is 600 gallons of gas, which amounts to $1200.  Now we're talking. #math
