Wow, a service station so 3 cabs can run 24/7!. If that is something to brag about because its difficult then welcome to the real world where we have slightly more than 3 cars.
Main issue is the high cost of batteries. You could imagine swapping old worn-down batteries for practically new ones. I wonder how to solve that.
Next step is standardising on a small number of batteries. If I see how many different tires are on offer I hops that will be solved as well.
Pie in the sky or a money pit. The only way there will be even 1 percent battery vehicle ownership in the U.S. in 10 years is if the federal governement forces us to buy them. Period. Mr. Wolf and his Better Fantasy are the latest in a long line of schemers and scammers who try to persuade people to follow them down the road to the impossible.
The battery-swap idea makes sense for a taxi company that has a regular schedule and can predict when and where they will need to swap batteries. It seems far-fetched that such a system can meet the needs of the general public. Batteries are very expensive, and it is not practical to have stacks of them waiting for customers that may not show up.
