One of the things that Autonomous Vehicles "know" best to do it is to keep the car behind the longways on the highway. But this function is only meant to help the driver behind the steering wheel, who must remain vigilant and ready to intervene in the emergence of a dangerous situation.
Unfortunately, from theory to practice is a long way, with the attention of drivers being difficult to keep for long periods of time when nothing special happens. The problem is that when the limitations of autonomous piloting systems are exposed in real traffic conditions, the time window where you can take action to avoid a traffic accident is as narrow as normal unassisted driving. Waiting for the car to react in their place, drivers come in too late or not, being completely taken aback by the situation.
Under these circumstances, may it be worthwhile wondering what is the usefulness of an Autopilot function if relaxation during trips is out of the question, the car manufacturer asking us to be constantly alert to what happens in traffic? Without the certainty that we can rely on it in any situation, the autonomous control system becomes a nervousness factor for those in the vehicle and a safety hazard
A controlled experiment, designed to demonstrate the limitations of the Autopilot function on Tesla vehicles and other semi-autonomous vehicles on the market, showed how easy an accident could occur if the vehicle suddenly changes direction, as often happens when the driver tries to avoid an obstacle on the way.
Scheduled to stop in the event of an obstacle, the computerized system does not have enough room to maneuver, but does not even act by initiating an avoidance maneuver. The limitation is intentionally left, so the computer can not reasonably assess each situation. For example, an automatic maneuver to avoid a harmless hurdle, such as a carton, could put the vehicle on a collision trajectory with another vehicle on the countersens or roadside obstacles. As a consequence, the only solution can be a careful avoidance maneuver even by the driver available to react in a timely manner
In view of the ease with which a vehicle's Autopilot function can be "tricked", an unintentional or even intentional maneuver of the driver may cause an accident involving the rear car. We take the example of traffic jamming, where a terrifying driver might unwittingly decide to "test" the vigilance of Tesla vehicle drivers or other car models that have activated the Autopilot function
