   Here is a first animation using it (sorry for the left-hand driving,
but I had to reverse the model so the plates and rear windshield banner
were right... :)

   http://youtu.be/vgQ-qMCdvhI

   I've changed his blue shirt for a plaid shirt: as the car was already
blue I wanted something different.

   Curiously, even if it is a static figure, my brain almost sees him
steering at some points.

   Now, I noticed a few more problems:

   + he seems to be glued to the seat, as car movement doesn't affects
him (I placed the model into the animation, not into the simulation).
   + OMG, he is riding without belt!
   + Wait... that Micra had automatic shift?

That looks good.

Marvellous, is it not?

The car's wheels wobble a bit as well.
I paid attention to them as I was thinking that if I gave you a series 
of meshes with the driver turning the steering wheel from -90° ~ 0° ~ 
+90°. You could select a mesh depending on the angle of the car's front 
wheels.
I am taking a couple of months off work so I have the time and I've not 
used Poser in a while. So I need to keep up my skills.
No pressure.

He is glued to the seat in fact  he intersects with the seat.

Not a public road so no problem.
Besides he is glued to the seat. :-)

Now you are asking. :-)

But a model with one one hand on the gear stick would not be a problem.

You could have cut off his feet though ;-)

They will be invisible under all circumstances...

Yes, I noticed that too. It was less in the first animation. Jaime, 
could you control the rate of angular change of the fore wheels? Make it 
more gradual?

I have been told that the origin of left-hand driving came from medieval 
sword fighting and tournaments, like also the winding sense of stairs.

Ouch!

In that case I could cut him off at the waist. :-)

I heard that the winding sense of stairs is for defence of the building,
assuming the main hand for the sword is the right one.
So defendants get full movement range and assaulting get problems.
So, the rotation is not the same when going to the vault or going to the
roof, from the outside.

The English driving on the left side is due to the sheath being on the
left side (once again for the majority with a right hand for the sword),
and horsed-armed-men should not collide the sheaths when crossing. It
went to road and railway (and so far, trains on railway still "drive on
left" even in France), because most trains first came from the island
west of Brussels (but the spacing between the rails is due to the wide
of the roman empire's horse's ass). Due to the large influences of the
English Empire, many countries sticks to that convention.
Napoleon might have hated that convention for Europe, but how do you
explain that the continental north America also drives on the right ?

Last note: trains run on left, but tramways is a different story, and
metro/tube too, they run on right (like car) in Paris.

On the continent, /only/ in France trains are left-sided, if I am 
correct. ;-)

No, all it shows is that when tasked with walking in a straight line, 
their compensation for any such bias they may or may not have works even 
when blindfolded.

Yeah, but it's one of the little tweaks by which they influence /what/ 
they sell (to an average person; they don't care much about 
individualists) - and also how much. Like that old trick to put the milk 
way at the back, because almost everyone has milk on their shopping 
list, so they make you walk past all the other goods that you might not 
have thought about when you made the list.

I've first heard that a quarter of a century ago, at a time when - or so 
it seems to me - juju wasn't state of the art. Besides, it's such a 
trivial thing that you can't really "sell" that idea - and the shop 
owner can easily check whether it has any effect or not.

Sure. But my point is that the continental bias is more natural :-)

Which, as far as I'm concerned, is a compliment.

Wikipedia claims that Belgian, Italian, Portugese, Swedish and Swiss 
trains don't drive on the right (!) track either. Some Austrian railway 
lines also drive on the left.
