There's an additional wrinkle for cars that make them unlike other devices, which is that they drive on public roads. I can't drive on a public road without a license, and neither should software.

But if little Johnny wants to drive his Tesla around a private racetrack with homespun Autopilot software, by all means! It's hardly the weirdest hobby, and who knows—maybe he'll grow up and form a startup that uses modified Tesla's to transport products in large warehouses. That's how innovation happens.
