Well deaths per billion miles driven on the autobahns are half that of the fat wide USA...
Also the autobahns I just drove weren't much different to UK motorways - never even saw a four laner. And they also don't have the Christmas tree lights + video walls on a gantry every mile either (but probably sell this amazing tech to the rest of the world)!
Just back from there and cruising at a speed that would cause you immeasurable legal grief here was very comfortable for me there at around 110mph (dependent on traffic density - sometimes more - sometimes less) - but then of course that's all totally different isn't it... Its just doesnt compute!
You want people doing 154mph on 8 year 1.6mm tyres on dual track then?Also the autobahns I just drove weren't much different to UK motorways - never even saw a four laner.

That isnt the case in germany.

No of course not - especially in the wet! But its clear that they have evolved with a lot more common sense and logic over there rather than any persistent and ever decreasing nanny/dumbing down punitive approach. Its all bit out of context on this thread so worthy of a chat elsewhere.That isnt the case in germany.

Just remind me, how did this bit come into the story? 
My cars I see don't get new tyres until they fail an mot,that includes mechanics and so called petrol heads.Germans have a much better mot system and culture.
I have on more than one occasion wasted a lot of money on new tyres for cars which subsequently failed their MOT because of something too expensive to fix.
I might drive a car with close to the limit tyres for a short while if necessary, but definitely not at very high speeds, and even more so on wet roads.

I've only address the comments made by people who seem to think that the speed alone will make people die; it doesn't. All your other comments are another matter and you need to address them to someone else.
More aggravating is I would only attempt that sort of speed on a motorway not the A11.The speed doesn't kill is all about cash only works on folk who are a relatively small margin over the limit.
If this conversation was about 98mph for arguments sake I might well agree with you. Once you start doing double the posted limit anywhere and your not properly (Police advanced) trained advanced driver, there is a much more increased level of danger to you and the public. Even paramedics and standard response drivers won't get to go that fast.
If there is no emergency and your just speed testing your car, your essentially using the PUBLIC highway as a race/test track and thats dangerous and selfish.
Having worked in highways and design (HE)), highways england do not design our roads for more than double the posted limit. Most barriers and highways furniture is testing to DMRB standards, which is you have guessed it tested to 30-70 max in most cases. If this chap had lost control at 154, he might well of ended up on the opposing carriageway, which could of been messy. Which is why only a handful of elite police drivers will ever been allowed legally to drive at that sort of speed and that won't very often.
You say you'd only attempt that speed on a motorway and not on the A11. Many motorways are in a really crappy state, full of pot holes and bad repairs. Many motorways were designed many, many years ago for a different era, with completely different performance levels of cars. Yet the A11 where he was caught is a essentially a brand new road with a beautiful surface, designed to modern standards.No sharp bends and good lines of sight.
It's a 70 limit so all the highway furniture and barriers will be tested to motorway standards, so if you want to drive at these sort of speeds it's probably a very good place to do it.

You have a very strange logic.

Indeed. I don't even begin to understand the first sentence of his response to my post plus I notice he studiously avoided answering my question. Instead he just repeated his point about no UK roads being designed for such speeds. You say you'd only attempt that speed on a motorway and not on the A11.

+1 I have recently driven several stretches of motorway where the surface leaves a great deal to be desired. So bad that 70 can be dodgy, never mind more than double that.

Leaving aside the legality or wisdom of doing 154 mph on a public road, here's a little quiz for anyone who's interested:
You're doing 154 mph on an empty motorway when you see a car ahead in the distance doing half your speed, and you decide to slow down in case he does something silly.
So, when you're 150 metres from him, you apply moderate braking and decelerate at 4m/s^2
How fast are you going when you pass him?

Pete317 said:
Is that tested to 70mph using a car, or a HGV?
They are tested to 70 with a car normally.Safety barriers are tested to European Standard EN1317, which is a standardised performance test. A barrier designed for normal containment would be tested with a vehicle of 1.5tons (an average car) hitting the barrier at an angle of 20 degrees at a speed of 70mph. High containment barriers would be tested with a heavy commercial vehicle, up to 38 tons, travelling at 40mph, hitting the barrier at an angle of 20 degrees.
On the mod base I worked on we had stanchions tested to 40mph for a 7.5tn lorry.

here in lays the issue as the vastest majority of the 'expert drivers' complaining about speed limits wouldn;t pass RoSPA /IAM / standard response ... When should we worship and faun?

Just a question.We have a nightmare section of road coming into Hull called Castle Street.There are a few pedestrian crossings which in my opinion are downright dangerous.Small metal barriers near the crossing and thousand of heavy goods lorries thundering by every day 40mph.If anything went wrong what change would pedestrians have to survive a lorry ploughing through these railings? None I presume.

It's not possible to knowingly slow at a given rate without setting some equipment up first, so I thought it a pointless question.
I haven't bothered to work it out myself as it's a pointless question, but are the answers "you'd never pass the car" correct?

So there was no accident this time, you are right. The problem is that Mr Howlett had no control over whether there would be an accident or not even when someone was just driving absolutely normally 300m in front of him.
PS That is the correct answer mph1977 said:

I feel I'm a pretty good driver but I know at silly speeds I'd be partly a passenger at my own wheel. No thanks.
