Good point Reynolds.
Equally though, consider whether all speed cameras are actually sighted in accident blackspots rather than hidden behind signposts, trees, etc. and whether the speed limits are appropriate. Driving at 30mph through a housing estate (whilst perfectly legal - except where a 20mph limit is applied) is potentially far more dangerous than doing 100mph on a quiet motorway. Just for clarity, the three figures on the M25 occurred at 2am.
You have clearly been taken in by the government con that "Speed Kills". That's quite a sweeping statement which tries to justify a money making exercise. 7% of accidents in the UK are attributable to excessive speed. The phrase should read "Inappropriate Speed Kills". Unfortunately, the government would no longer be able to justify extorting money and removing the driving licences of hard-working honest people.
