Alternative Fuels?

The most recent spike in gas prices has me wondering if the perpetual increases will ever stop. I, like many, am almost to the point where I am going to seriously alter the way that I drive. Upon initial consideration it appears absurd that we haven't either come up with commercially viable alternative ways to power vehicles or come up with better long term strategies for gas consumption. I keep hearing the argument that to make an across the board change to another fuel would be impossible. We would need to completely overhaul our infrastructure, our cars, etc... Nothing short of a JFK moon vision, they say, will change this.
If the biggest obstacle to change is the fact that we are so far along the gasoline path, why don't we explore other types of consumption in developing nations like China and India. I don't think that they have the massive infrastructure dedicated to gasoline that we do and as they develop why don't they do it with the myriad options that supposedly are out there? I imagine that I am really simplifying the issue but is it even being considered. If you haven't already sunk so much into a dated and infinite resource such as gas wouldn't you want to explore other cheaper and cleaner alternatives?
I know that this would cause headaches such as having machines that are compatible with both types of fuels, dealing with the oil cartels, getting everyone to buy in etc... but I don't think that they are insurmountable. I guess I'm just sick of hearing about all of these great alternative fuels and not seeing anything done about it. China or India would be great places to test them.


Meanwhile in the time that it took me to post this rant gas prices have increased $.03.
