Remember Betamax and VHS? That’s what will happen to electric and hybrid cars. Hydrogen power has a few snags to sort (like being slightly flammable) and will take off thus bringing down cost. The problem with electric is charging points. Ok for BMW and Jag drivers who can park car on drive but what happens if you park on the street.
90% of the time our cars are sitting on the drive. Driverless cars will make booking your car by type for the journey only will become the norm, like a taxi. Most of the cost of a taxi today is the drivers time. No driver, less cost. The second most expensive element is the fuel. Hydrogen is driven by water and side product is oxygen.
What is the biggest stumbling block is human psychology. We can run driverless cars but will society let us? Hydrogen cars are here. Most manufacturers have versions.
