I dislike the idea of "self-driving" cars on the roads. Every computer uses algorithms and there are always many kinks to work out. The greater the scope and variable factors in the program, the more kinks there will be. The largest issue is that unlike normal software where most, if not all, environmental variables, can be controlled, a self-driving car must function in the real world in an environment where many variables cannot be controlled. A mistake in an algorithm can mean the difference between life and death when it is powering a two thousand pound hunk of metal along a busy highway.
