I get where jim is coming from. Human behaviour is tricky but it operates on patterns which can be coded to series of data sets. Say for example in a highway, u are driving 100kph, then suddenly there's human being suddenly crossed the street. With human driver, bec he often drives that road with same speed, if he's not distracted he might see the pedesatrian and react instinctively but lets say he's distracted, then might not be the case. As for the computer, before the pedestrian ctoss, the side cameras can already him, calculates his movements how fast he is moving, velocity etc then computer can make multiple calculations.
