Cars

As an item in this world that is so clearly unsustainable, it amazes me just how popular the car is.

The majority of drivers seem blissfully unaware of the alternatives to the car, or the fact that it has a limited shelf life.
During my (pushbike) commute to work, I pass by car drivers, looking rather grim at the prospect of sitting in traffic, paying a fortune for fuel, rego/tax and having to use the car to get to a job they don't want to do, to help pay for this misery.

Once inside the steel clad box, most rational people seem to feel that they are invincible, from the weather, other road users and rational thought. This may be because there are so many safety systems in cars these days (which ironically I played a part in the development of) or it might be because they are in denial.

Which ever way you look at it, the car's days are numbered, so go get a bus timetable or a nice recumbent.
