I believe the surging fuel prices, which will double in 10 years or less, is a way to ween the population off petrol. It's running out and these prices do two things:
1) Make a sh!tload for oil owners, refineries, governments and distributors, and
2) Will make owning a petrol powered car so impractical that alternative fuel will become the standard.
This second point will do two things:
1) Give other market sectors (biofuel developers/producers, hydrogen cell developers/producers, electrically powered/hybrid developers/producers and engineering departments of large automakers opportunity to mass produce new engines and cars) the massive profits associated with a passenger transport renaissance in which we turf all our current vehicles and buy brand new ones which are incompatible with older technologies.
2) Begin using alternative fuels, at which prices are set at whatever the bloody hell these industries deem reasonable.
All i really care about is that we don't continue to rape the environment, which is what the extensive international political debate has been doing over the last decade.
I'm looking forward to seeing what the Jap and German engineers can do for the future of the internal combustion engine. I think there will be a market for it when we're all 70-80 y.o. There's a new BMW 7-series powered by hydrogen using an internal combustion motor. Jay Leno drank the water which dripped from the exhaust tip
