“As for letting the cart go back to the private property, I don’t know how far the cart was from the private property, and I don’t know if avoiding public streets was possible.”
But you posted, without conditions, that you would have let them go.
This is Florida, not Missouri. Illegal carts on the roadway is a problem. Driving at night with no lights is not just “bad judgement”.
I placed TWO conditions on letting them go. If you think that is "without condition" then I don't know what to tell you.
