text: This can either be a pro or a con. The drivers have to stay alert and take over when the car needs it. They aren't made to know how to go around traffic and roadwork, so when the car sends an alert the driver can take over. I take this as a pro because it seems safer than leting your car try to work its way through roadwork on its own. When you have control you feel safer, but this can also be a con. When you hear "Driverless cars"
