Do they realize that, in a car crash where the ammonia tank is punctured, everyone around it dies a horrible death?

Implying crashing with a current fuel system does not carry the same risk and you cannot make the tank safe. None of these implications are true. Any energy source carries risks and most of the risks can be mitigated.

From the article:

Puncturing the hydrogen tank is pretty bad too. The death is less horrible and much quicker, however.

The proposal here is to crack the ammonia back to hydrogen which is then used in a regular fuel cell car.

Would you store it in the car or feed into a pressurized tank in the car? If that's the case, you still have the problem of storing the hydrogen in the car.

We already store pressurised gasses in cars, specifically CNG vehicles.
