Question

what are the disadvantages of driverless cars? check all that apply.
they always drive slower than surrounding traffic to avoid accidents.
they cannot tell the difference between people and other objects.
they will wait for crossing pedestrians even if signaled to keep driving.
they may unexpectedly drive off the road to avoid potential hazards.
they will not allow the human driver to take control while in motion.

Explanation:

• Option 1 (They always drive slower than surrounding traffic to avoid accidents): This is not a disadvantage; driving slower for safety is a positive aspect or a safety measure, not a disadvantage.
• Option 2 (They cannot tell the difference between people and other objects): Current driverless cars have sensors and systems to distinguish between people and objects, but limitations in perception (e.g., in complex or low - visibility scenarios) can exist, and this inability (if present) is a disadvantage as it can lead to accidents.
• Option 3 (They will wait for crossing pedestrians even if signaled to keep driving): Waiting for pedestrians is a safety feature, not a disadvantage.
• Option 4 (They may unexpectedly drive off the road to avoid potential hazards): Unexpectedly leaving the road can be dangerous, as it may cause accidents with other vehicles or objects, so this is a disadvantage.
• Option 5 (They will not allow the human driver to take control while in motion): If a human driver needs to take control in an emergency and the car does not allow it, it can be a serious disadvantage as human judgment might be needed.

Answer:

B. They cannot tell the difference between people and other objects, D. They may unexpectedly drive off the road to avoid potential hazards, E. They will not allow the human driver to take control while in motion
