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.

Richness breeds complacency and egoism. In rich nations most cars just transport a single person from A to B.

Only a few people in industrialized nations are willing to use their own bicycle or any other less fuel guzzling means to transport themselves. Sure there are many people who use public transport – but those who use cars usually ride alone.

It’s such an irony, since most cars simply transport themselves, because that single person hardly makes a difference moving a ton of metal and plastic.
