Because you have been taking lessons from harry?

Does "no one" include Toyota, Hyundai and Mercedes?

There are a handful but they are decidedly experimental. The problems of
handling very high pressure hydrogen gas and not poisoning fuel cells
means that they are mostly concept vehicles rather then production ones.

Running cars on natural gas or methanol is a more practical proposition.

I was at a green energy promotion held in Trafalgar Square where there
were several large scale fuel cell systems that claimed to be able to
power phone exchanges. But not one of them was working. Power to the
entire exhibition was provided by several noisy smelly diesel electric
generators on tickover. I was impressed with the electric motorbike.

The only fuel cells actually running to make power at the event were the
educational toys intended for school science projects driving LEDs.
I found this profoundly disappointing YMMV.
