text: I think we should have smart cars, but with the right percautions and keeping an element of human control. Sensors giving warnings and keeping drivers alert should be enough to help with the safety concerns. Stress is reduced in this situation because a driver has the help of the sensors, but is not relient upon it either. The systems that allow entertainment are too controled by a computer and cause issues with transitioning between relaxing and paying attention to driving. Driving still has to be taught and if a computer dosen't work humans still have the knowledge to take over without extra danger.
