text: The cars still need a little help from the humans when there is a road block, jam in traffic,work zones, or accidents. The car doesn't have the skills yet to navigate around things that can be in the way of the road or its course it was on. The driver will be alerted when the car has a difficulty and can't manage to reroute. These cars can handle only twenty-five MPH. Higher than that the driver itself will have to drive such like on a highway when you can go 60 to 70 MPH. Manufacturers have applied different kinds of alerts such as a vibrating seat, announcing itself, and another option could be flashing lights on the windshield. How do we know if those alerts will actually alert us. Everyone is difeferent and get alerted differently, how will the manufacturers know that any of these alerts will actually be affective to people.
