Ego has been moving in this direction. They basically have 2 or 3 models of batteries that only vary by capacity, but they are interchangeable with most of their equipment. The riding zero-turn lawn mower can use 4 to 6 of their 56V/10AH batteries at $500 each. The batteries are half the cost of that riding mower. Those batteries can be used with most of the handheld gear such as weed whacker, blower, lawn mower, chainsaw, snow blower, etc... I could see using the 10AH batteries on a bike. It would take a lot of them to power a car but I could totally see Honda making something that would be easy to swap out. Perhaps some day people don't even buy/own the batteries. One just pulls into a "battery station", lets the car drive and position itself into a bay, pop pop, off you go. Fully charged reconditioned batteries. Even faster than buying fuel. After the car leaves, the previously used cells are tested straight away and if faulty, they get routed to a recycling center. If in nominal shape, they get recharged and put back into service.
