I seldom ever stop for red lights, as they generally have turned green by the time I get there.
Do this and you'll save a bunch of bucks on gas, not to mention your brakes will last 3 times longer, and you will double the life of your drivetrain.
I agree with you except having too much air in tires, esp. in a pick-up, one needs all the patch pressure traction & grip possible to avoid looking like a retard on ice skates when things get hairy.
A few pounds under rec. can keep from wrecking.
MPG don't mean a thing wrapped around a tree.
I've also found buying the best tires you can find & keeping them fresh & a little under inflated is not only safer but cheaper.
I have 224,000 miles on a 93' dodge dynasty with the original ball joints, tie rods, etc.
The fresh soft tires have taken all the shock load not the car, my spine is ever thankful too.
My experimental emphasis has always been on comfort, safety & longevity.
You'd never make it driving around big city suburbia where there are stop lights every 100 yards, esp. on the streets loaded with strip malls ;-).
I tape an imaginary egg to the bottom of my shoe.
