text: There will come times where the car would not be able to move. This may happen when there is an accident and the car can't get around it; or when there are a lot of opsticals around like work zones. You would still need to be alert for when car alerts you to take over. This may be a reason why people might want to get a driverless car, but all you have to do is drive around the opstical or park which isn't a big deal. After you do that you wouldn't have to drive anymore. There could still be accidents when you are driving or not paying attention when you have to take over the wheel.
