The problems with hydrogen have never been with using it as a fuel source. The first problem is storage/transport of the fuel and the second is what happens to a vehicle with a hydrogen fuel tank when it's ruptured in an accident?
I can see a train making sense - a lot more space for storage and cooling, plus the risk of an accident is very low. But I haven't seen anything about these issues being addressed in motor vehicles.
If by "savvy", you mean flubbing your location to somewhere in the developing world where that's the price point, I refuse to do that. I have no issue pretending to be in say, Germany and taking up a 75% off deal. But I won't put myself somewhere where the regular $10-$15 price point is genuinely out of range of the locals.
If too many people fake their location to these places, the Googles and Steams of the world will stop giving those nations lower prices. I won't have my own selfishness take something away from thousands of people.
