It's more efficient to simply use hydrogen.
I don't understand why anyone would be convinced by arguments like this that don't include numbers, when you can make the argument sound equally valid on either side of the debate.
The overall losses in Germany are 7%. [1]

Only if you fake your numbers by an order of magnitude, see above.

Still better than your astroturf numbers. If hydrogen is better, so be it. However, the Tesla S can go 450km with one charge today and it can be charged everywhere.
An electric car is the nightmare of traditional car manufacturers: an electric motor costs nothing and lasts unlimited kilometers. You need no engine oil change, the brakes last a lot longer and cars will easily last 1.000.000 miles / kilometers and a lot more with little maintenance. You do need to change the battery but this is not money for the car manufacturer.
So there are two huge industries for which e-cars are a nightmare: petrol and classic car manufacturers.
Disclosure: I drive an MiEV an it works amazingly well.
