After reading this, I actually went to the order page and read what Autopilot would eventually give us.:
"
Autopilot combines a forward looking camera, radar, and 360 degree sonar sensors with real time traffic updates to automatically drive Model S on the open road and in dense stop and go traffic. Changing lanes becomes as simple as a tap of the turn signal. When you arrive at your destination, Model S will both detect a parking spot and automatically park itself. Standard equipment safety features are constantly monitoring stop signs, traffic signals and pedestrians, as well as for unintentional lane changes."
It's hard to believe that the current hardware will allow for all of this. Monitoring pedestrians and stop signs? Automatic lane changing? Does the car really have a 360 degree view?
