New petition to getthe Government to raise motorway speed li

This must the 100000th petition on the same subject. 
Perhaps more relevant now though with more and more speed cameras on motorways.The problem: no real evidence that speed limits improve road safety.
The solution: change speed limits within RCT scientific trials (eg 90 on some motorways with others as controls, randomly selected from pairs).
Scientific trials would provide the evidence but, while the Authorities don't want evidence, do we?
It will get vetoed by highways England and brake.
Highways England say it will increase accidents. They have proven slowing traffic down reduces crashes and congestion.
People near motorways will moan about noise and an increase.
Pollution will be another reason and the reason the government dropped it previously.
Traveling at 80mpg burns 15-20% more fuel in my experience. Studies say more like 20-25%.

80mpg , that must be a diesel. 15-20% more fuel than what? Thing is though , faster you go the less time you spend in any place and the slower you go the more time you spend kicking out emissions.

Can I recommend you put your arm out the window at 50, 60, 70 and 80mph to get an idea of just how much resistance your hand (and your car) have to push through to travel at faster speeds. This is what increases the fuel consumption and the amount of emissions your car emits, not the time on the road. konark said:

Than 70 mph I'd assume. Aero drag at 80 is 50% higher than at 70, and is the main source of resistance at those speeds. You spend 14% less time in the area, but use 50% more energy doing it, so energy used per mile would be about 30% higher, hence emissions in any given area will be higher (probably not 30% higher, but 20% ish seems reasonable).Thing is though , faster you go the less time you spend in any place and the slower you go the more time you spend kicking out emissions.
I'll probably get shot for saying this and normally I'd be for raising the limit but I'd say it wouldn't work in the UK. I have a pretty quick car and I can't really use it as other road users don't seem to be able to judge speeds. Alternatively, maybe we as a society have reached a point where our own self importance means we won't wait for other road users to pass, we'll just pull out or stick an indicator on (oh it's OK to pull in front of me now then) and that means you have to break or back off the accelerator. With cars going faster, I can only see the 55mph, oh I want to be in the outside lane now morons causing a lot more accidents.
I'd like to see variable limits, maybe raise them depending on conditions and time of day but that would mean investment in signage up and down the country and would probably cause more confusion.

As a performance car owner I have to agree with this.I'd like to see variable limits, maybe raise them depending on conditions and time of day but that would mean investment in signage up and down the country and would probably cause more confusion.
