I drove 1800 miles in a Hydrogen Car

I think if battery based EV can combine Hydrogen into hybrid EV; we can get the best of both world. In emergency or important to get to point B, refilling Hydrogen. For daily drive use electric charging.

The danger of combustible in hydrogen put into the vehicle is no more than the risky of flammable petrol in ICE and Lithium battery in EV.

If in the future scientist can produce vehicle that using non flammable power source/storage is the holy grail of green solution for transportation.
