You know what will change the world?
When governments finally give bicycles a chance, like in the Netherlands. THAT solves a multitude of issues, saves incredible amounts of money for both governments and citizens alike, and will lower the car death toll by a vast majority.
Oh, and it also lowers pollution (yes, EVs still pollute) by factors and saves tonnes of energy as hauling two tonnes of steel to buy a bottle of milk is just insanity
That ignores the full self driving for a second, which still doesn't exist anywhere and won't come into existence for another good decade at least (We're FAR away from that) but that will be the real revolution
