Those early vehicles were not very complex, and the batteries would obviously be far smaller to operate them. Heck — they were probably comparable to what you’d have on a moped today.
Obviously vehicles are much more complicated, especially since the invention of the semiconductor and the subsequent advent of solid state technology. But, the topic is battery storage. Batteries have evolved and improved no doubt. But, they’re still lacking in range, recharge capability, cost, etc. the world has been waiting for “the big breakthrough” in battery technology for one hundred years and is still waiting, waiting, waiting...😉
