Agree with so much said here
I've had this same discussion re "speed kills" many time.
Wrong.
Inappropriate speed kills. Poor driving kills. Tailgating and not paying proper attention kills.
We have a crazy system in the UK and there are some fairly simple solutions that would generate revenue and I believe to some extent lower costs to individuals.
First off - scrap the road excise duty. It isn't even as if it goes towards maintaining our piss poor road infrastructure any more.
Replace it by increasing the cost of petrol and diesel a few pence a litre (bear with me).
As part of this cost increase, implement third party insurance for everyone.
This has three immediate benefits:
No one can ever drive uninsured, be they foreigners or just some jumped up idiot;
You actually have a pay-as-you-use mechanism that means people like me, that have driven over a thousand miles a week for work in the past pay the appropriate amount of money for this whereas my wife, who struggles to put in 1500 miles a year doesn't pay the same as me;
You can scrap a lot of the DVLA.
Stop this crazy law whereby my son, when he hits the age of 17 can pass a test and so long as he can afford the costs associated with it can then take a Ferrari out on the motorway the day he passes.
Let's make people have lessons and possibly another test even before they are allowed on motorways. Ditto before they're allowed to drive powerful motor vehicles - hell, you have this mechanism with motorbikes.
Make people take tests more than once (another revenue generator and allows people to keep up to date on the most recent highway code - my 70+yo neighbour passed his test almost 60 years ago. The roads haven't changed much since then...?)
Let's have sensible speed limits - like others have said, let's make them genuinely variable and let's have traffic police officers back on our roads that can use their own judgement and common sense.
And if you lift the speed limits and people are caught tailgating, for example, or blasting through the lower ones in fog/rain then hit them hard.
Oh and as for the comments about lower insurance costs - I traded my ageing Porsche Boxster in lately for a Focus CC - the insurance? It went down 24 quid a year...it really is a protection racket.
