As much I read, the difference between "standard cycle" and realistic driving is currently at 30-40%. And I guess, there is no realistic way, may you be a good driver as ever possible, to reach these consumption levels. And I don't agree: The tax incentives are also made by the government and the taxes are of course based on the official (forged) numbers. Also when you argue the fuel tax will make it right: No, I don't agree, because the consumers can not decide -- they are also lied at with the wrong numbers!
