I’re read a lot on line about hypermiling. The way I understand it, you use the inertia you build up in your car as much as possible. Use the gas pedal and brakes and little as possible.
Doing this on Southern California freeways is difficult. You need to leave plenty of space between you and the car ahead of you so you don’t use your brakes so much to slow down. That’s darn near impossible here. Nearly any space big enough for a car has a car in it, or will have in seconds.
But I’m trying. A lot of it just seems to be thinking ahead. If there’s a red light in front of you, take your foot off the gas and coast up to it. Less gas getting there, less time and gas sitting at the light and a chance it’ll turn green before you get there. I don’t follow trucks closely enough to use their draft. I like breathing.
There are two problems with the whole thing. One, I have to pay attention. I can’t just drive around on autopilot. Two, I’ll never know how much gas, if any, I’m saving. I started doing it without ever checking how much mileage I get in the first place.
