I believe using a metal hydride "gas tank" would be pretty heavy and I don't know how many miles worth of fuel you could carry. I'll take a look at the link you provided.
Also, that would still require someone to fill the car with gaseous hydrogen and also the infrastructure to deliver across the entire country/world. There is already the infrastructure to deliver gasoline and/or methanol.

The tank is just a tank, of normal metal of composite. The hydride is in the form of small metal balls, coated with plastic. They test the integrity of the balls by boiling them in water, so they are quite safe to transport. You drop the ball into the tank of water, then puncture the plastic coating to allow it to react with water.
