That part of the video starts just after you drove past my kitchen window. The 101 South is posted 55 mph from the beginnings of Studio City almost to the junction with the 110.
What you filmed is exactly what I've observed there many times- nobody bothers to slow down to the posted speed limit. This may have something to do with the fact that I hear the SKREEEE...BLUNCH! of yet another idiot wiping out a couple of times a week when I'm at home.
Never mind saving fuel and money- taken as a whole, Angelenos can't be bothered to observe a speed limit even to save their own asses.
water4gas improves gas mileage AND reduces emission toxicity towards zero.
here is the proof.
