India is actually technologically advanced it could probably do a similar thing.
It's Pakistan's reliance on rivers that originate in India (from mountain ice packs that are rapidly depleting due to climate change) and the long-standing tension between those two nuclear armed countries that raises concerns.
Hydrogen fuel is being looked at as well with a recent fairly large study in I think 8 European cities on hydrogen buses (only one I looked at was London) though that relies on better ways at producing hydrogen. The study seemed to conclude that it was good but without a way to produce it better was not really very worthwhile.
Yep, the common criticism of hydrogen is that it is an energy sink: It requires more energy to produce than can be stored in the resulting hydrogen fuel. So, running buses on it at this stage is (IMO) both a publicity stunt and a waste of resources.
Biofuels are also fairly interesting though I need to learn more about them.
Oil-rich algae that can be grown in saline environments is the most promising so far, but biofuels of any kind are not widespread enough at this time to be a hedge against the consequences of peak oil, which is happening right now.
We haven't reached the maximum extent of our resources just the maximum extent of the ones we seem to use there are a lot of untapped resources which we NEED to start using. A lot of things I read in Engineering & Technology (E&T) tend to suggest that the future will see us replace oil with lots of different technologies and not just use one resource. E&T is published by the IET, the professional body for all forms of Electrical and Electronic Engineering in the UK.
Just as an aside we have enough coal reserves to provide at our current rate for something like 150 years. Clean coal is quite an interesting resource.
And as a further aside we should probably take this to another thread if want to continue it.
Do we currently have enough ships, trains and trucks operating on "clean coal" to weather the impact of oil prices spiking into the hundreds per barrel and maintain our access to critical resources? If not, it isn't going to be much use to us over the next couple of decades.

I agree though, we have certainly wandered off topic, but in my little brain all these issues are inter-related. Subsistence cultures are infinitely valuable because they are resilient, while ours is not. IF anything goes terribly wrong here and the groceries get too costly, my bug-out plan is to go native. IOW, go and join a community that has never entirely given up a subsistence model of social organization and learn how to support myself from them.
Granted, that's got nothing to do with gypsies. lol. I suppose if we're going to stop trying to force indigenous people to assimilate we might as well lay off the gypsies while we're at it.
