You sound naive and people are mocking you, but honestly who knows. Maybe theres nothing holding this back other than AI skepticism.

The proper way to find out is to get some peice of heavy machinery and try it out. Maybe not a tractor neccesarily, but something that presents a similar quality of risks, even if at a smaller scale. Maybe a forklift?

I think its a bad idea so i wont do it, but why dont you?
