The Bike Hod is indeed more prone to incorrect loading. However,
that must be balanced against the other factors which make it better
than alternative designs for a number of uses.

The bottom line is that few people have one set of clothes, but
rather several sets which they use as appropriate. The same is true
of trailers and bikes.

Indeed. I gather Mr Cameron lives in Notting Hill and I am unaware
of any terrain between there and the Westminster parliament where
using one would be a great problem compared to its advantages.

If the Labour Party had introduced a law saying that in a few years
time cycle helmets would be compulsory then your point would have
validity.

The Westminster parliament could indeed bring such murders up again.
However, in order to put such murders into effect they would need to
undo a fair amount of other things. IIRC it is a condition of
membership of the EU not to have such murders.

I am trying to think of anything.. The only hill is Constitution Hill,
and even that is pretty flat.

Especially if it is a standard A4 sized box placed low down between the
wheels. It does predicate not hopping on and off pavements.

What is the width of a Bike Hod? Obviously a worf style trailer will
be too big. The Carry Freedom ones look very nice. And of course he
could take his kids in trailers too..

Do I believe he is telling the truth? No idea. He might be the same
sort of slimeball as Mr Liar.

However, my point was that others need to make their mind up.

You can flip a trailer on a straight road. If a bump and /or sidewind
(and I speak from bitter experience*)) cause a wheel to lift, the other
wheel will try to trail straight behind the coupling. Which means it
tucks under the COG rather quick. The geometry of the Bikehod makes them
especially prone to these mishaps

It involves London streets which, at most times of day, amount to much
the same thing...

But omitted to mention that he would replace it with the Conservative
Party's slightly different one?

A little narrower than a "standard" door.

Which standard? That'd be about 70cm then?

I thought excessive speed was supposed to be the main factor when that
happens. I've seen it done - once with a caravan, once with a low, flat
trailer, and both times the vehicles were travelling considerably above
50mph.

I wouldn't have said the road was particularly bumpy on either
occasion, but how bumpy does it need to be for this to be a factor?
Maybe it needs to be only a very slight bump if the vehicle is
travelling excessively fast.

I don't recall what the wind conditions were like on either occasion.

....which, ahem, they have.

But to put my point in a less terse and cryptic fashion: whatever law
has been enacted, it remains the case DC is promising to abolish
something that doesn't yet exist. Unless he is thinking of abolishing
passports and driving licenses (and it would be impossible to reverse
the requirement for biometric passports unless he wanted to prevent all
UK citizens from ever visiting the US ever again). And whether ID cards
will ever exist in the originally proposed form is still far from
certain.

And when you can steal a person's identity using nothing more than a
discarded boarding pass (see yesterday's Guardian) what difference will
it make whether or not DC abolishes formal identity cards?

It's not cynical to ask what exactly he is promising to abolish, or
indeed if it would be in his power to abolish it anyway.

And it's certainly not cynical to accuse a politician of making empty
promises.

Not so likely to happen with a bike trailer then!

What's all this about Worf? Worf is a man with a ridged forehead, and Google
agrees with me. He's not a bicycle trailer. Or maybe I just haven't seen
that particular episode yet, where Worf designs a bicycle trailer from an
ancient Klingon design, and neglects his duties on the Enterprise? ;-)

That's equally true (or untrue) of a tricycle. Or a car.

Google doesn't agree with you if you use it appropriately...
