Cars = Stupid, Stupid, Stupid.

Disclaimer : I've owned 4 cars in the 16 years I've been legal to drive. 3 were cheap bangers 13+ years ago, my current I've had since '99 and was mainly bought for two reasons :
a) Having a kid more or less makes a car essential, having a teenager makes you an unpaid taxi-driver ;)
b) I work freelance, so not having a car restricts the places I can work a lot.

The car, to me, is the single purchase which most clearly defines all that is wrong with 'Western Civilisation' :
It's individualist and about personal freedom primarily, and doesn't give a toss about the common good.
It brings out the worst characteristics in people.
It's use leads to people being killed and injured, a lot.
It has lead to our destroying large parts of the natural world to accommodate it's use.
Worst of all, it's not even a good technological solution - Cars are woefully inefficient and , superficial changes and materials aside, haven't changed design much since the days of the Ford Model T.
It's one of those things that everyone knows should be scrapped and replaced with a better solution but nobody has the vision or balls to do so - The classic, "But we've always done it that way." excuse.
Until we can take a good hard look at nonsense like driving around in piles of metal powered by dead fish bits, each of which is generally piloted by one person alone, progress of the human race is going to very slow. If indeed we can progress without going into a decline brought on by our use of such 'non-sensible' solutions...
