Because EVs kind of suck when you want to transport things. Most countries have weight limits relative to your driver licence. I'm not allowed to drive any car whose weight is more than 3.5 tons (and that includes what you are currently carrying). So, instead of a 150kg engine and a bunch of gas, you now have at least a ton of batteries to carry around for your vehicle to be somewhat useful. And that's before everything else. So now, an artisan can only bring around 1 ton of crap, instead of the 2.5 he could before. This is even worse for long haul trucks.
