It's the opposite. The rules are well written by people who understand the issues. It's the regulators and courts that have had problems understanding.
That's basically what Android is. The APIs can run on any base OS, and for a while Microsoft maintained a subsystem for Windows. CPU agnostic too.
Chinese machines are already making inroads where they aren't banned. You can get a lot of decent construction equipment from there too. That's the danger here, by the time Western companies get around to producing EV tractors with all the advantages they bring, the market will be saturated with mature and competitively priced products.
As for durability, some EVs have proven to be very fixable. Nissan Leafs are a good example. Relatively simple, not difficult to work on, drivetrain that is separate from everything else and highly maintainable. Again, the Deeres of the world are screwing themselves with all this DRM bullshit that stops people fixing their products.
If you need health advice, check some European country's public health agencies. The UK's NHS has a decent website with information on a lot of medical conditions.
Thanks, that's informative. If I had mod points they would be yours.
