I am willing, but only if everyone else is too. I think that's how most people feel.

When it comes to what transport mode is best for the environment I basically am a toddler. I don't actually know what's best. I need to be told what's best by one having a prohibitively high price.

I don't even need to claim that it won't work, I can just point to evidence and you can see: it does not work. People are taking the plane because they can afford to.
