For automakers, the worst problem of electric vehicles is that maintainance/service is easy and they make more money servicing vehicles that from selling... but it can be fixed: 1- renting batteries (and still charging annual service fee). 2- renting whole cars by the minute using a mobile app.
The problem with Hydrogen is that's still an _explosion_ motor with a different fuel, and you have to develop a new kind of motor for it plus a way to store and consume the hydrogen cells safely.
If anything, I see it will be more profitable for automakers as they will continue to charge the same service prices as they do now for less and simpler work. Plus they can make up new maintenance like Toyota have done with their 'hybrid battery health check', which is a paid optional extra, but extends the battery warranty for one year.
There are no hydrogen wells. So you'd have to use a lot of energy to make hydrogen fuel in the needed quantities. And then (because it's such a light gas) highly-pressurized containers (collision-survivable) are needed.
Instead, use that energy more directly.
That would include not posting personal attacks, not insinuating shillage, and not creating accounts for every few comments you post.
