My young son lives on his own, has a poor paying job and just had a baby with his live-in girlfriend.

He was putting the squeeze on me for gas until it started to get to be a weekly pinch. Finally, I put the kabosh to that and gave him a three-speed so that he can commute to work. He knew better than to try to convince me that bicycling is not practical.

So now, despite the winter cold, he is bicycle commuting - not because he likes it, but because he cannot afford gasoline.

So, I can tell you that right here today in the USA is at least one person who is bicycling for the single reason that gasoline prices are to high for his family budget.
