Not much worse than cars in the UK, remember that the US gallon is 
smaller, so 34 MPG here (which is about what I get out of my 10 year old 
Saturn coupe) is about 7 L/100 KM (or about 40 MPG in UK Gallons if I've 
done my math correctly).

The Prius owners I know (a couple) typically get 55-65 MPG (in US 
gallons).  That'd be 66-78 MPG in UK gallons.

"identity of indiscernibles" is the phrase you want.  And at any rate, 
that conflicts more with your use of the term "reflexive", rather than 
"transitive".  But hey, you got "symmetric"! (and the gist of the 
others, I'm just pulling your leg).

Too much information.
La la la la la. ;)

Aren't all cars upgradeable with just software nowadays?  In my car the 
"1.6L", "1.8L", "2.0L" and "2.3L" versions all actually have exactly the 
same engine.  You are just choosing whether you want the 116, 143, 177 or 
204 BHP software installed when you buy it :-)  I heard some people got up 
to 265 BHP out of that engine, but to me that seems really stupid as all the 
other components will not have been reliability tested at that power level.

My Megane is petrol, although I gather there is a diesel version of most 
of these cars now. And yes, diesel has completely different performance 
characteristics.

Erm... 1.6L means that the engine block has a displacement of 1.6L, 
while 2.3L means that the displacement is 2.3L - i.e., the cylinders are 
physically bigger.

The Real WTF of course is that displacement is not directly related to 
power output in the first place...

The bit where it says take away the number you first thought of.

Nice one BTW :D

Heh. Somebody had this printed on a T-shirt [as you can probably tell]. 
I just copied the image file. ;-)

That's apparently the Milner-Hindley type inference algorithm. But whatever.
