Stooo wrote:The government has admitted that its proposal to increase the speed limit on motorways to 80mph would lead to more pollution and increase the risk of road deaths. Transport officials also told the Guardian that there would be no widespread roll out of 20mph limits in towns – a measure that is reportedly a concession to the Conservative's Lib Dem coalition partners.
Transport secretary Philip Hammond said the existing 70mph limit was "out of date", and that Britain needed to be "back in the fast lane of global economies". But the Department of Transport said that no impact assessment has been made of the proposed speed increase, only an "initial analysis".
http://www.guardian.co.uk/environment/2 ... sfeed=trueIs this a good idea considering the fact that cars are less efficient at highers speeds?
At the moment people are being encouraged to conserve energy whereas this proposal is surely a backwards step.[/quote

Cars are more efficent at higher speeds than lower. It takes more energy to move two ton than to keep it moving.
I never understood why a cars designe wasn't limited to 20mph, 50mph and 120mph?
The weight and fuel consumption of a lighter car designed to reach a speed of no more than 20mph could not be used for local needs.
And the lager 120mph limited to being used at 80mph, it is definetly designed to use as much fuel as can be.
If you actually consider how often you get an oportunity to reach a consistant speed of more than 40-50mph, there is little point in increasing motorway limits by a measly 10mph. It is quite laghable!
What dose concern me is motorway pile ups are more common and can easly involve up to seventy vehicles. Not neglecting the arrogant ignorance of large (5-10 ton) vehicles stopping distances by general domestic drivers, I can see more laws comming from it! More likely directed towards commercial trucking companies!
If not, then increases in domestic licence costs as well as other abstract regulations that domestic drivers will be charged high prices for.
