@strypey Heh, "the market" will sort it out, right? ;-) But more seriously, it's got to be better than pumping fossil fuels, and if integrated into a transportation system that includes good public transport, rail networks etc. that reduce road traffic, and thus demand for fuel for personal vehicles, it would be a net improvement, right? I think a lot of people reject anything and everything that wouldn't result in being able to maintain the *current* way of doing things, as if all of that would be a retrograde step. And it's not like the proposal is anything like using food crops to make ethanol or biodiesel, which make much less sense, but I think some people apply the same logic. I suspect NZ has different specifics than here (the UK) but I doubt the thinking is a lot different: "you're just trying to take away our right to (whatever)" without accepting that there's a whole other, better proposition. Anything that is likely to make the rich less rich, or improve the environment, is always portrayed as something that will make the (already terribly unfree) poor, less "free".
