Interesting fact: In elliptic geometry, pi is less than arcsine 1. In 
hyperbolic geometry, it's more than arcsine 1.

I thought England was already surrounded by water...
did the Chunnel turn it into a peninsula of France?

I think the idea is that the channel will get *wider* to compensate for 
a better Prius (whatever that is).

A car made by Toyota that has much lower CO2 output than most other American 
cars :-)

...but Toyota is Japanese...?

More importantly, I gather that most American cars are horrifyingly 
inefficient, so beating that shouldn't be too hard I'd guess. I don't 
really know.

They sell a lot in America though.

I think that's why they sell a lot.  The issue in Europe is that you can 
just go and buy a small efficient diesel car for half the price of the Prius 
and it will have similar CO2 and mpg.  So there isn't any reason to get a 
Prius.

Oh, I see. I thought you meant that American cars sell well because 
they're horrifyingly inefficient! :-D

It's less than arcsine 1 where you're sitting right now. That's why they say 
gravity bends space-time.

Toyota is *originally* japanese. Like any giant manufacturing company in 
industries heavily tariffed, they have plants all over the world, including 
the USA.

Not especially. They're *bigger* than what you find in downtown london, for 
the most part, but the Prius gets something like 40+MPG while still holding 
four people plus a bit of luggage.

Heck, my Renault Megan holds 5 people and gets roughly 45 MPG.

[Or rather, it did until recently... I haven't figured out why it's 
suddenly started rapidly decreasing.]
