Hydrogen vs. Battery Electric Cars

No mention of where the majority of Hydrogen, or Blue Hydrogen as it's called, comes from... GAS.. So not as zero emission as Hydrogen claims to be. Also, why take the electricity to make Hydrogen with its inefficiencies when it can go straight into the car. Plus, if all cars were suddenly electric, the grid wouldn't collapse as the reduction in electricity used to make petrol and diesel would make up for it. The point that would be a problem is the current cabling going to all the houses would not be able to cope without being upgraded and/or charging managed. There are BEV cars coming out with 500 miles. BEV cars do have their problems and there is still a long way to go.
