But what's the range of a 'practical' hydrogen car? (one where all the cargo space is not taken up with hydrogen tanks.)

Both hydrogen and battery cars have the same obstacle to their take-up: infrastructure and range.

When there are as many recharging stations for hydrogen and electricity as there are normal petrol/gas pumps, those alternatives might finally be viable.

Where do you live? Here in Europe everybody I know has electricity at home. I only know one person who has a petrol/gas pump (he runs a gas station).

I realize that you are being a bit over-the-top, but most people don't have high-voltage, high-amperage circuits in their homes in the US, and the vast majority of apartment dwellers, even those who have reserved parking, do not have a way to connect a high-wattage charger to their car that will also bill to their apartment.

So if you're limited to fast charging, it is relevant how common the chargers are.
