Proposed 60 mph speed limit, Will it REALLY cut pollution? Options

[x2lls]

My view is that I don't believe it will.
Yes, a constant speed is almost always the most efficient way of using fuel, at the right speed that is, but with the high volume of vehicles on the roads, will it actually work?

I suspect all it will do is bring down the average speed of those that usually drive at 80 plus, to a slightly lower level. Does driving faster actually increase the volume of pollutants expelled? After all, the fuel is only being burnt at a faster rate at higher speed, so surely a litre burnt in say, an hour as opposed to thirty minutes will still convert to the same amount output, only over an extended period of time?

Hydrogen DOES have infrastructure. There are existing petrol filling stations along with LPG stations. We can utilise 90% of the existing infastructure there, would just be pumps etc.

Not until they are empty of petrol.

Big, big farts!

The SERIOUS point I was trying to make is that 60mph speed limits, running on electricity, hydrogen etc. is a futile gesture in the big shape of things. Cars & small vans make up a minority part of carbon emission / pollution caused by burning fossil fuels.
A 60mph speed limit, buying a Prius, or running your car on hydrogen will not much change the total emissions and their effects.

I think the idea is for a ripple effect and to encourage public debate. Even the USA and China are becoming more concerned about emissions. This issue will run for generations, but that isn't a reason not to start somewhere.

I was hearing on the radio just this week that smog is a huge issue in Asia, enormously more so than here (nowadays anyroad).
