Companies produce Mercedes-Benz S550 sedan, Cadillacs,  Volvos, Tesla Model S which show the future of transportation. Communication systems and sensors installed in the streets (intelligent roads ) and cars have opened new avenues. Getting around will be cheaper, more convenient, and environmentally friendly. Advanced cruise control lets a vehicle drive itself on freeways. Radars and cameras can keep it within a lane. It keeps a safe distance from vehicle ahead. It automatically  brakes and steers to keep pace with the traffic. It cannot handle sharp turns. It responds to emergency situations — say it senses you are off the road into the median or the vehicle ahead is on the brakes. Cars can take advantage of the telemetry data. Tesla will introduce self-driving feature called Autopilot as a software.
