Most Westerners waste precious fossil resources by  travelling alone in their cars or on their bikes. In developing nations cars, motor bikes and even push bikes are for mass transport.

If you travel alone on a car 95% of the petrol will be wasted  to move the car – not to transport you.

If the distance allows it than use public transport or a bike – or a small vehicle with a better weight to passenger ratio.

Westerners should see cars and motorbikes no longer as cool lifestyle choices(for their penis or social status), but as serious tools to be shared with others. The age of unsustainable individual transport has to come to an end.

A recent strike in London forced many people to commute the old fashioned way: by foot or by bike. Substitute buses picked up the moving masses and many people remembered the fabulous idea of car sharing.

It gave us a glimpse into the future of mass transport: we eventually have to use our own bodies again or "share" more.

While oil prices going up again using a car will be unaffordable for many and even public transport will become more expensive as well.

Unless we change from a oil based transport system to a renewable energy transportation will become very expensive. But also urban planning has to be improved in the US and Europe to many cities have sprawled to far apart, making daily live more like a long commute / drive from home to work and back.

Cities and communities used to be more integrated: living, shopping, learning, entertainment and work much closer together.

Cars used to be much smaller and used a lot less petrol. Compared to SUVs these old Autos look like toys, but they were much less thirsty.

Today’s cars spend most fuel on moving themselves forward – the passengers weight make hardly a difference.

The 1967 VW Beetle weight a mere 840 kg and a Toyota Prius NHW20 Hybrid 1,317 kg. Just for fun: the Hummer H2 weighs an amazing 2903 kg.

Each kg saved makes a difference and especially today we have so many tough , but amazingly light materials. So lighter cars should be no problem at all.
