The vehicle rolled backwards and hit a predestination with no one in the vehicle on level ground. I don’t know why it rolled backwards since it has never done this before unless someone had hacked into the computer system and caused it to go backwards. I also don’t know if this car has the lvl of technology that can be hacked as in the completely driverless vehicles. I only know the theory of computer science and smart technology, I don’t know if my car has advanced enough technology for someone to remotely hacking into the car causing it to move backwards or not.
