I used to let my kids drive earth movers and buckets when they were 11 or so (a couple dozen yards or so), and let them move the bucket up and down and break earth and concrete
I’d probably be doing hard time now
I did the same with my son when he was 12.
I don't know the laws on that island but I live on the coast of NC where there are a lot of golf courses. It is very common to see kids driving their golf cart back home on public streets. A golf cart can't be licensed for street traffic, so why would you need to have a license or be "of age." We have a cop live in our neighborhood and his kids used to drive the neighbor's golf cart on the streets. No one ever gave it a moment's thought.
