Yes life is easier in Kilometres, Kilograms, and Litres. For a start it is the standard of science, even America science (oh and American Sci-Fi, I guess at least in the future America uses metric).
Changing to metric would also help a little with those God Bothering Religious Right types.
You see the Imperial system works in series based on six, why six? Well it could be because people use to believe "the world was made in 6 days". The rest of the world dropped that idea years ago and used a numeric system that is based on ten, and why that number?
Look at your 2 hands, count the digits, the metric system is as self evident as the rights given to them (your hands) by god, even if its impossible to cleaning divide ten by any number other than by five and two.
Why does America not change to a system that is so simplistic it is at the tip of your fingers, because "We have always been imperial, always will be!"
"We have always done it this way", is always a bad argument, it never beats "We do it this way because it works!"
What is almost as strange as the imperial system is the way America counts it's votes.
In Australia (and many very stable Western Democracies) we count every vote by hand.
In Australia's case at the last election, by this slow and old fashion method, we had a result with in two hours, and guess what? They matched the exit poll's! No conspiracy theories went around, no recount asked for.
It's a simple system, you get people to vote on a paper ballot, and you then put that in a locked box. When the booth closes, people get together, unlock the box and hand count every vote. When everyone agrees to the count they are then sent to the main tally room, where they are put together with the other booths.
It’s all very transparent; in fact the general public can watch the count at the booths. Not many bother, because they trust the system, mainly because the exit polls match the results, which match the general polling done ahead of Election Day.
Pollsters in Australia have never had to apologise for getting it as badly as America's did in New Hampshire last week, or dare I say, in the General Elections of 2000 and 2004, where both exit polls called it for the Democratic nominee, but we still ended up in the end with that Idiot Bush.
No machine counting is so beautiful, elegant, and honest.
Come on America give us an election we can all believe in, chuck out your hackable Diebold machines, and get together and hand count the vote, after all god gave you ten digits to do it with!
