Spend money on roads to cut global warming.

A typical family car with a top speed of 120 mph needs about 121bhp to drive it at that speed. Since the power needed to move that car through the air at half that speed (60mph) goes down by the square root, it can be seen that just 11bhp would do the job. The other 110bhp are only really needed for overtaking and joining fast traffic. If roads were wider then overtaking would be easier and need less power. If acceleration lanes were longer we could join up with fast traffic without needing to accelerate so hard. We need not then have to buy cars with powerful engines just to stay safe and to avoid inconveniencing other road users. If roads were better then we could also avoid traffic jams.
You see where I am going? Better roads would save energy and reduce the rate that Homo sapiens is polluting the atmosphere. A spin off from this is that better roads are safer.
It is easy to blame motorists for having accidents at accident black spots but has anyone considered that our road infrastructure may perhaps need a little money spent on it?
I would not hesitate to advocate a rise in fuel duty to pay for this – except that the money raised in this manner would undoubtedly end up like the ‘road fund’ license. It will be taken from tax donor and used for other ‘worthwhile projects’.
