text: The cars that have been developed still need a driver. What's the point of having a driverless car, when you still need a driver? Some people who don't fully trust the concept, like me, need some control. That's why some manufacturers are "bringing in-car entertainment and information systems that use heads-up displays" to alert the driver when he/she needs to take over. Many manufacturers have developed an alert system, GM "has developed driver's seats that vibrate when the vehicle is in danger of backing into an object". Some others include a simple announcement and flashing lights.
