This is kind of why you need fuel cells or similar.
People are obsessed as a fill up is potentially long and potentially you end up queuing for a while too.
Then you have the do they work, is there infrastructure, that 300+ mile range is really only 175-200 in winter on the motorway.
Due to that range is super important as people are nervous and don't want to get stranded.
Fuel cells work great, but supply is terrible.
If they got even 25-50% of petrol stations to have a hydrogen pump, then that's a fantastic supply network. If that happens you sell an EV with a 30-50kW battery and you have the option of a fuel cell range extender. Suddenly it's cheap to buy, perfect for town and if you want the safety of long range then you tick a £2000-3000 option box, which is way cheaper than a huge battery. One design, one battery so cheaper to build.
Sure hydrogen might start blue, but with the cost of oil it will move to green pretty quick, especially with the correct taxation of blue vs green.
Baby steps in the right direction is better than no action.
People are not obsessed as such, they're worried.
I admit I've been wanting a hydrogen Fuel Cell car for years, but then it's due to the fact I don't want to tow half a tonne of batteries when I don't need them.
In fact if they can design a car where the range extender can be added/removed as needed as a module, I can think of a very profitable holiday business
Public transport barely exists here and so that's why range matters. Visiting the family would require a top up somewhere even in a 300 mile (WLTP) range car.
