You're actually using the hydrogen instead of inefficiently turning it into electricity and driving electric vehicles with it, so I'm not sure why you thought this was relevant to bring up in a discussion about hydrogen fuel cell vehicles.

Completely correct observation. 70 % conversion of electricity to hydrogen 50 % loss for storage 70 % conversion back to electricity = 0.70.50.7 = 25 % efficiency. Absolutely abysmally low. Unless there is a lot of renewable in the electricity mix, it is even worse than ICE!
