Tread your way to fuel savings
According to Michelin chief Michel Rollier, 40bn litres of fuel have been saved because of more efficient tyres.
In a knowledgeable and frank discussion, he outlined how there will be:
* 1.5bn cars on the road in 30 years -- up from 800m.
* huge advances on what tyres can 'do'.
* They will be taller, smaller and far more efficient. And that could mean saving a lot of money on fuel bills.
But will the garages keep prices high and governments continue to take a huge wad of tax on petrol and diesel? That is as big a challenge.
