Consumers Confused by Partially Automated Driving Features

What's in a name? When it comes to partially automated driving systems, apparently a lot.


The latest research from AAA indicates that 40 percent of U.S. consumers believe partially automated driving systems can do all the driving---a scary proposition for all drivers on the roads.


Names such as Autopilot, Pilot Assist and ProPILOT allegedly confuse some drivers who don't pay attention to their surroundings because they believe the cars handle all the driving chores.


In addition to the confusing names used by some automakers, researchers at AAA also tested multiple systems in four vehicles and determined they suffered from serious problems when dealing with stationary vehicles, poor lane markings and unusual traffic patterns.


To research partially automated vehicle capabilities, AAA conducted tests on the closed surface streets of the Auto Club Speedway in Fontana, CA. Additional tests were conducted on highways and limited-access freeways in the Los Angeles area.


Researchers used a 2018 Mercedes-Benz S-Class, 2018 Nissan Rogue, 2017 Tesla Model S and 2019 Volvo XC40, all equipped with standard partially automated driving features.


While driving on public roadways, the test vehicles had problems in moderate traffic, on curved roadways and when traveling streets with busy intersections.


"Researchers noted many instances where the test vehicle experienced issues like lane departures, hugging lane markers, 'ping-ponging' within the lane, inadequate braking, unexpected speed changes and inappropriate following distances,” stated AAA.


According to researchers, the systems typically did best on open freeways and freeways with stop-and-go traffic. However, nearly 90 percent of events requiring driver intervention were caused by the inability of the test vehicle to maintain lane positions.


Closed-track tests were conducted by using multiple driving conditions such as following an impaired driver and coming upon a tow truck or a vehicle that suddenly changed lanes to reveal a stopped vehicle was in the road.


AAA said all the vehicles successfully maintained lane position and recognized and reacted to the presence of the tow truck with little to no difficulty.
