This "AI Lawyer" is about a traffic ticket. If we want to make things more fair while also enforcing the laws on the book it seems like the more straightforward tech solution is to improve traffic cameras/monitors such that tickets are given out more appropriately. Or, if it still goes to court, why not just have a system where someone can represent themselves with a form or checklist which points out the reasons they were given a ticket by mistake?
Perhaps this is a good business model in the current system but its definitely not the best for society as a whole. Why do we need lawyer of any type to handle something as banal as speeding tickets?
