There are also electric F1 cars in development, and an increase of hybrids development is happening.
Fossil fuels, while still abundant are being slowly phased out, even thought "green" replacements for them are nowhere near ready for market, nor anywhere near being able to replace the capacities.
Presently, there is no replacement for fossil fuels, unit for unit. That doesn't seem to bother the environmentalist wackos who would push us, prematurely, into the use of green technologies.
Don't get me wrong, I understand the need, and the inevitability, I don't understand the rush. Green technologies will happen, and will eventuality replace the use of fossil fuels, it's just not there yet. It's the type of thing where we will have to have both technologies coexist for a number of decades before the fossil fuel technology can be retired, but that doesn't seem to suit the environMental Nazis.
We don't have the green technologies, AND we don't have the infrastructure to take advantage of that technology, even if it was efficient enough to replace fossil fuels.
Anyway, it's a sure bet that sooner or later electric cars and Harley's will be the norm, and the gas powered stuff will be museum pieces. The hard core "I'll drive my gas powered car, anyway" guys will come to know the advent of $100 per gallon gas, exorbitant registrations cost, and insurance costs (if it's still legal, at all to run a gas or diesel powered vehicle in the future).
