You and I are usually on the same page but I disagree with you statement of "yet a damn 8-9-10 yr old farm boy (no license) can drive a multi thousand $$ tractor/combine/etc on the roadways". I grew up on a farm and I did operate all the farm equipment we had at a very young age as you indicated in the fields. But I could not and did not drive on the highway because it is just as illegal as an adult not properly licensed.
