I read recently that in France it was British Engineers that built the 
first railways. So, you guessed it. The trains ran on the left.

Okay, you win.
It is not worth going to war about.
(I can be magnanimous. Especially since I am right.) ;-)

My understanding is that we just kept what the Romans did.
 From Wiki.
"In 1998, archaeologists found a well-preserved track leading to a Roman 
quarry near Swindon, England. The grooves in the road on the left side 
(viewed facing down the track away from the quarry) were much deeper 
than those on the right side. These grooves suggest that the Romans 
drove on the left, at least in this location, since carts would exit the 
quarry heavily loaded, and enter it empty."

Not only in France. Which, to be fair, isn't much of a surprise given 
you guys' edge in the matter back then.

I think that Jaime and Stephen did a very good job here. All the stuff about
hearts, livers and so on is only guesswork IMO. Pychological studies often lack
statistical significance, especially with such exotic topics. BTW I'm driving on
the left side of the road now for one week (and the following) with a
left-steered car from France and it took me only seconds to switch to the
English system. It as naturally to me as the German right-side driving. One
gests accustomed very soon.

Best regards,
Michael

That's an interesting one! I take note.

One can suppose that left-handed fighters were sent to just those places 
to even out the odds.

   Yes, I still have to investigate why this happens, as the wheels 
constraints on the simulation shouldn't allow this movement. It happens 
much less if I reduce friction, but then it looses too much traction.

   Yes, that is totally feasible, as I can export such data from the 
simulation.

   Unfortunately, I've had only a week of vacations this month, but 
should be able to work on it on the weekends.

   Yes, I had to place it manually, when it should have fit perfectly 
given that you placed it over the actual seat used on the animation... 
I will look at it again to understand why this happens.

   Ah... yes, no problem then.

   Don't worry... the acceleration is constant and fixed, and I'm not 
going to implement a gear box on the simulation. :)

Your opinion is my opinion too.

That does not surprise me one little bit.

Be careful when returning home.
After driving 4000 miles on the Continent in a RHD car. The first thing 
I did when returning home was to drive on the wrong side.

If you have any time and are going to London before returning home. We 
could have a London PovCon.
