Perhaps we should just bring back horses. BI as in biologic intelligence. Where I'm from it was common merely 100 years ago to exit the tavern, plonk yourself into the wagon, let the horse free and fall asleep in pleasant stupor. Usually the horse had no issues finding its way home. Usually. Sometimes it supercharged itself on a nearby pasture. Crashes were uncommon.

If you think this is sarcasm, it is not. That horse was clearly more reliable, adaptable and performant, not to mention safer, than anything Tesla or Wayomo is offering today.
