So here's a way you can do it, without force.
Take your savings, in fact set up a company, and speculate on oil futures. Buy as much as you can. It must be a safe investment, and watch your capital grow.
From the massive windfall profits you make from this, use it to invest (you always say invest) in public transport. Hybrid buses or indeed new trains. By then peak oil will be so obvious, that you could have borrowed from the bank to do so. People will be gagging for public transport so much, you'll get many investors willing to join you. New Zealand has a free market in public transport, just set up a bus company and go for it. In fact, the government may be happy for you to buy trains and run them on its track.
Run services, charging fares to cover costs (you're not into profits), so that people get the alternative you care so much about. Yes the trains may take longer, but surely with the empty roads you predict, the hybrid buses will operate with ease, quickly and efficiently, full of eager fare paying passengers.
Not willing to put your money where your mouths are? Well keep your hypocritical hands off of everyone else's.
