@vulcao If you really, really need them to drive on asphalt roads, maybe hire someone to make sure it doesn't become a danger by monitoring it. Make sure they have access to controls to take over from the AI if something goes wrong. In fact, save the cost of the AI entirely by having this person always be the one in charge of driving the vehicle full of people, and now you don't need all that expensive computing equipment and cameras, you just have to pay one person's salary.
