In fact pushing a vehicle with an electric motor does not require it to hook into the botnet. My grinder has an electric motor, yet hackers can't touch it.

Lithium enough to make the batteries necessary for us to have enough EVs does not exist on the planet, however, so EVs aren't going to suddenly replace infernal combustion engines until better batteries are available.

Pushing a vehicle with an electric motor, as you suggest can be done by using various chemical fuels and a turbine to create requisite charge to turn the motor, is simple and far less complex than ICE engines. This is hard to overestimate as a plus when it comes to durability, and decreased maintenance costs.

As 3D printing becomes more ubiquitous, I expect we'll see many more people rolling their own cars, and using hybrid systems to power them using chemical fuels to produce electricity onboard that powers electric motors. I am confident we'll see folks making their own PCBs and chips too, which is going to eliminate the factory backdoors that enable the panopticon.

Chips don't have to be superminiaturized, after all. Eniac was huge. While we can't print microscopic circuits (yet) we can certainly print simple circuits for our bespoke vehicles. They only need to be small enough to fit in the structure of the vehicle. Cars are pretty big, and there's room enough for a lot of printed circuits incorporated into the structural components.

Thanks!
