| | Here is where predicting what people will do in response to either what governments mandate or even what other people do is not simple. If higher taxes are imposed, instead of changing from fossil fuel to something new most people may just give up some other purchases and continue driving gasoline fueled cars. Also, I am told by those who have followed it, gasoline prices today do not amount to as high a percentage of people's expenses as they used to. Which suggests that, relatively. gas prices are lower than they were in, say, the 80s. Also, and I am only speculating here, suppose cars are more efficient now as well as more enjoyable, reliable, and attractive--all of that could prompt people to keep buying them and paying higher gas prices than before.
