One of the sources I was talking to was an engineer from Mercedes Benz. Even Mercedes are predicting the take-up of electric vehicles to be huge and are forecasting a decline in oil consumption. Interestingly he and others also said that algae-oil, that is, making crude oil from algae in a pressure cooker will eventually make extracting crude oil from the ground un-economic. But that's not going to stem the rise of electric cars & trucks. Audi have even made diesel from water & CO2.
My main question is will the stable oil prices give a new life to the quads.
