That's not exactly self-driving if it's on a pre-programmed track and has a low max speed. Be realistic. You're comparing cars that go 70 MPH with very sophisticated assist features with a cart that couldn't outpace a runner. Please.,(reply>), pre-programmed track?<br><br>Are you aware of how the computer navigates? Did somebody show you the programming?<br><br>In fact this cart travels will less of a pre-programmed track than a human driver.,(reply>), What we didn't see is what happens when a pedestrian passes in front, If it doesn't hit them. I'd call it a driver-less car. Roads are pre-programmed tracks in a sense.
