    I know people streamline cars and things and it increases fuel efficiency. But, would it increase efficiency further to streamline them in such a way it improves the 'drafting' of lines of vehicles? We all drive with other people on the road, so I was thinking if cars were designed not only to be streamlined individually, but streamlined for each other, it would increase fuel efficiency.

    That's tailgating isn't it?
    What you gain on fuel you'll lose on fines! 8)

    You'd need to be pretty close to benefit, a lot more fuel efficiency could be gained by learning to drive efficiently - or using computers to control the amount of fuel (as some cars do now) - slowing down early by 'aero-braking' rather than using the physical brakes of the car. If you've ever noticed you get nowhere near the fuel efficiency figures quoted by the manufacturers it is because they drive very carefully - it's quite a skill.

    Or you could 'get out and walk' apparently a huge proportion of journeys are a very short in distance.

    hit the nail on the head there billco, more walking helps with fuel efficiency always makes me laugh when you see all the mums in 4litre range rovers dropping there kids off at school and being stuck in traffic(cause all mums are doing the same)to go 5-10mins round the corner from where they live.

    then they complain about it and scratch their heads cause there kids are getting fat and lazy too

    Captain caveman, I walk or cycle, - Makes me laugh, I walk one of my grandsons to school (about a mile and a half) It's quicker than in the car, much healthier. I heard a (Greenpeace)joke recently it might appeal to you.

    Q: What is the difference betwen a 4 by 4 and a hedgehog?
    A: The hedgehog has the pricks on the outside!.

    One day I'll get to understand it.. :wink:

    One way to increase MPG about 4%, which was new to me, but trucking firms have evidently done for years is inflating tires with nitrogen.
    The larger molicules don't leak out and keep tires running cooler.

    opening the windows is a sure way to increase mpg and in the uk when we have big england games on theres alot of cars with small england flags that clip to windows to show support. there was a report that said that if you put £30 of petrol in your car you use an extra £1 in fuel just for one of those flags(which are 8" by 4" roughly)flapping in the wind
