I feel that that at 70mph, the 2 sec rule between cars is an inadequate
time to avoid a pile up.I would say more like 4 secs.


It takes 3s [best] to physically stop from 70mph and probably 4s in a real
situation (e.g. something fell off a bridge onto the motorway, HOWEVER the
car in front of you can't just stop dead either, so 2s is fine for sensible
driving.

Indeed. My other favourite stupid quote is that a car hitting you head on, both of you doing 70, is the same as hitting a brick wall at 140.

I hate it when people compare Clint Eastwood to God. Don't get me wrong, he's incredible! But he's no Clint Eastwood.

As I was taught when first learning to drive, better late in this world
than early in the next.


"Hello, St Peter - nice gates. I wasn't expecting to be here quite this
soon."

overtaking? Betcha thought it was just oncoming traffic and shat your
pants when you saw pearly gates."

Probably considerably worse. Brick walls are a suprisingly survivable
target for cars - most walls just give way in a shower of bricks without
doing much more than trashing the front of the car.
Hitting another car, on the other hand, is much worse - as is hitting a
tree.

Given the choice of hitting a brick wall or a tree, I'll take the wall
any day.

So, can I get an injunction against (a) my 8yr old son, and/or (b) the
government?

Alex Heney spoke:
I was in a very dense, quite slow moving line of traffic passing the
results of a minor accident that was on the hard shoulder (with police
in attendance), Because I *was* looking further ahead, I saw something
"puff out" from ahead towards the central reservation , and had my
brakes on before the car in front of me. He was the in fact still
quick enough to be the first not to hit the one in front. It finished
up with SEVEN cars all piled into one another, and we hadn't been
doing more than about 40 to start with.

Forward observation can back-fire though.

M1 southbound one summer in 1980's. Lane 3 'making progress' 80mph-ish,
spotted trouble ahead, brake lights and much swerving, so slowed a
little and dropped into lane 2 and the cause of the cerfuffle became
apparent - and complete ring of a shed truck tyre sitting in the middle
of lane 3 - which the car still in lane 3 ahead of me completely failed
to notice, he hit it and flipped it neatly into the middle of lane 2
just ahead of me!

I had no choice or time to do anything other than drive straight over
it.

It took the bottom half of the radiator and most of the exhaust away!

A "crossover" from the opposite carriageway can stop a car dead.
It is admittedly rare.

It's so rare it can be discounted in the normal scheme of things ...

Which is the main factor making motorways the safest roads in the UK.

Like that PPI-ambulance chasing firm that keeps ringing me? I've never
had PPI, my number is ex-directory and we're on the TPS list - that
means anyone ringing me is automatically a black-hat - but they just
don't seem to grasp this.

My niece on her driving test was doing 70 along a dual carriage way and
saw in the distance a lorry parked in a layby signalling right. She did
all the right things to change lanes about a quarter of a mile back,
much to the puzzlement of the examiner.
What he could see but she couldn't was that the lorry had its hazard
lights on - there was a car parked behind it which blocked her view of
its left indicator.
He asked her what she was doing and she explained - which was just as
well as he'd hoped to turn right at the roundabout ahead!

I got a text from one of those nefrubyrf yesterday. I've never had PPI
