People are confused and wrong about driver assistance systems, IIHS finds

Autoblog

A new IIHS study found that a scary amount of people are confused about the driver assistance systems found in cars today. Furthermore, the study found that folks were especially confused about Tesla's Autopilot.

One portion of the study involved the IIHS surveying participants about certain unsafe behaviors behind the wheel, given only the name of the driver assistance system. People weren't given the name of the brand for this section, and were instead told to answer the questions about Autopilot (Tesla), Traffic Jam Assist (Audi and Acura), Super Cruise (Cadillac), Driving Assistant Plus (BMW) and ProPilot Assist (Nissan). The results show that folks misunderstand Tesla's Autopilot far worse than any other driver assistance system on the market. A chart of the results is pasted below.



A huge 48 percent of respondents thought it OK to take your hands off the wheel while using Autopilot. Additionally, 6 percent thought it safe to take a nap with Autopilot active. This level of distracted driving is something we've seen time and time again on public roads. Interestingly, only 27 percent of people surveyed think it's alright to take your hands off the wheel using Cadillac's Super Cruise, and that's a hands-free system.

We should be concerned about the numbers for the other driver assistance systems, too. Drivers are confused about the capabilities of current systems, and what a manufacturer calls it appears to be contributing to the confusion.

The IIHS study went further to learn about how people are interpreting instrument cluster data as it pertains to these systems. This portion of the study used a 2017 Mercedes-Benz E-Class. It found a couple different bits of information eluded most of the study's participants. Most people "struggled to understand what was happening when the system didn't detect a vehicle ahead because it was initially beyond the range of detection." Also, many were unable to identify when lane centering was inactive. The IIHS suggested that audible alerts and more obvious visual signals could help improve the understanding of these systems.

Results from another IIHS study were also released today, and this one has to do with where people are using these systems. This study monitored people driving a Range Rover Evoque and Volvo S90 to see where and how often they use adaptive cruise control or the Level 2 Pilot Assist system in the Volvo. These systems are meant to be used on the highway, and are often detailed as such in a vehicle's owner's manual. The study found only a small percentage of driving off the highway was done using these systems, just 7 percent for the Evoque and 11 percent for the S90. Those numbers both rose considerably in highway use, with the Evoque's systems being used 40 percent of the time and the S90's for 28 percent of the time.

Volvo will limit top speed on all its vehicles to 112 mph

Volvo has announced that it will limit the top speed of its cars to 180 kph, or 112 mph. The carmaker says it wants to send "a strong signal about the dangers of speeding," and from 2020, no Volvo cars can go faster than that. The limit is part of Volvo's Vision 2020, which aims for zero road deaths or severe injuries in a Volvo by 2020. Polestar models were not mentioned.

"Volvo is a leader in safety: We always have been and we always will be," said HÃ¥kan Samuelsson, president and chief executive. "Because of our research, we know where the problem areas are when it comes to ending serious injuries and fatalities in our cars. And while a speed limitation is not a cure-all, it's worth doing if we can even save one life."

Volvo's flagship XC90 SUV currently has a top speed of 131 mph.

Samuelsson, speaking ahead of the Geneva Motor Show, said it is unlikely to meet the Vision 2020 goal without additional measures to address driver behavior.

"We've realized that to close the gap we have to focus more on the human factors," Samuelsson told Reuters. Volvo did not elaborate on the data but said its passenger fatalities were already well below the industry average before the goal was announced in 2007.

In addition to the speed cap, Volvo plans to deploy technology using cameras that monitor the driver's state and attentiveness to prevent people driving while distracted or intoxicated, two other big factors in accidents, Samuelsson said.

There's also nothing preventing these Volvos from being driven at 60 mph in a 30 mph zone yet, except for proposed EU-mandated automatic speed limiters. But Volvo is also looking into limiting lower speeds with technology. Volvo's statement says: "Apart from limiting top speeds, the company is also investigating how a combination of smart speed control and geofencing technology could automatically limit speeds around schools and hospitals in future." In other words, if drivers cannot be trusted to make the decision to slow down, the cars will do that for them.

It has to be said the 112 mph limit is somewhat peculiar. Even if Japanese home market cars have had the same speed limit implemented for ages, there aren't that many countries where you can legally pass 110 mph. European highway limits are usually around 75-80 mph at maximum, and crashing at 90-100 is already dangerous enough. It feels like Volvo has set a limit no one would ever reach in normal driving, except perhaps on the German Autobahn. Samuelsson conceded that the limit could be a turnoff for German buyers.

That also brings us to an another aspect of the matter: which more strongly affects sales, a message that a manufacturer voluntarily limits its cars from reaching a certain speed, or that the cars are guaranteed to attain a given speed that few buyers ever reach?

"We cannot please everybody, but we think we will attract new customers," the CEO said, recalling that the roll-out of three-point seat belts pioneered by Volvo in 1959 had initially been criticized by some as intrusive.

"I think Volvo customers in Germany will appreciate that we're doing something about safety," he said.
