No their not. If we were energy independent in the US we would not need to stablize the Middle East. We could have went all methanol in the 70's but the oil companies killed the idea.
Brazil went all methanol in the 70's. I heard the price at the pump (retail) is A$0.35 cents/litre which I think works out to about US$0.90 per US gallon (estimated w/o doing the math)
Lots of cars here run on liquid petroleum gas, which is more enironmentally friendly that petrol/gasoline. It costs less than half the price of petrol/gasoline, which makes big V8's relatively affordable to run. There is nothing like a V8

Well you mean ethanol in Brazil. They burn a 90% ethanol 10% water mix (I assume there is a denaturant in that ethanol perhaps unlead gas, etc). The engine are a higher
compression ratio to so they can run more efficient on the ethanol blend. I think the water serves to boost the octane number and since removing the last 5% water is very expensive it make sense to leave it.
Methanol can be made from coal.
water gas reaction
C (red hot coal) + H2O (steam) = CO (carbon monoxide) + H2 (hydrogen)
CO + H2O + heat + catalysis = CO2 (carbon dioxide) + H2
CO + 4H2 + heat + Catalysis = CH3OH (methanol)
In the real world natural gas is used to make methanol currently on small scale.
methanol can be dehydrated to dimethyl ether and used as a clean diesel fuel but it would require mods to the engine.

I will try to find the link to the history of how the oil companies killed methanol.
