A couple of points here:
1. Cheap subsidised fuel isn't going to go away any time soon. Most people simply do not have the basic intelligence to think about 50 minutes into the future, never mind 50 years. And most people are happy to become communists when it suits them.
2. More expensive fuel would not necessarily increase cycling or even reduce driving. My honest opinion is that most people would quite happily sell their own children into slavery if it meant they could put fuel in their car for another week.
