Hi,
There is a petition available to sign at the 10 Downing Street website for all those who wish to oppose the government's proposal to change the national speed limit from 60mph to 50mph.
http://petitions.number10.gov.uk/noNSLreduction/"We the undersigned petition the Prime Minister to Not reduce the national speed limit to 50mph."
"Following the announcement that the government is planning to reduce the national speed limit to 50 miles per hour, we the undersigned oppose this, since it will make no difference to road deaths and the cut in carbon emissions is so insignificantly small it's laughable."
