In one sense, it seems utterly premature to be raising awareness of this technology when you're driving a LHD car because there are so few about that it's not viable to build RHD yet, you have to live near one of just six stations, and not stray too far from the hydrogen highway otherwise you won't be able to refuel, there are no forecasts available for residuals, and the owners of such cars are simply companies who need the PR stunt.
Why bother? Well, primarily because, behind the scenes, all car manufacturers are on the case. This technology is coming, it's already here in limited numbers and the targets for acceleration of the tech are rapidly approaching: by 2020, for example, there will be 65 hydrogen filling stations in the UK. And the fuel-cell vehicles out there – the ix35, the Toyota Mirai and Honda Clarity – don't drive like wacky concepts from outer space; they drive just like normal cars, with the same production values and the same interiors. In other words, the technology is here, in a car you'd recognise and be perfectly capable of driving right now, and we all need to get our heads round it because what comes out of the tailpipe is water, not respiratory-threatening noxious oxides.
