Re: Lets lower speed limits because gas costs too much

Exponentially being the key word here. There are people much smarter than me that could explain it better, but as your speed increases over the optimum efficiency (generally 55 mph, modern cars are closer to 65 mph) the efficiency of your vehicle DROPS exponentially.

I have no idea how to solve this problem, but the fact is, driving fast wastes loads of gas. But if you're on 2 wheels you're wasting gas more efficiently. And don't tell anyone, but I've been getting less than 25 mpg on my RC (barely 80 miles before the fuel light comes on), with 93 octane!!!!
