Autonomous Cars: Even the Millennials are Losing Faith

In light of the recent crashes involving Tesla and Uber self-driving cars, two studies, one from AAA and the other from CarGurus, have been released showing that about three-quarters of consumers do not trust current autonomous driving technology.  

The first study, conducted by AAA, was a 1,014-person phone poll done in April, shortly after the fatal self-driving Uber crash in Tempe, Arizona and the Autopilot Tesla crash in Mountain View, California. The poll found that 73% of the participants are afraid to ride in a fully autonomous vehicle – a 10% increase from last year. This is compared to the mere 20% that said they do trust the autonomous driving technology. This is not, however, the most notable finding to come from the poll. AAA discovered that 64% of millennials are too afraid to ride in a fully autonomous car, which is a 15% increase from just four months prior.  

CarGurus’ survey consisted of 1,873 vehicle owners ranging between 18 and 65 years old. The survey, also done in April, found that 84% of the participants said they won’t or probably won’t own a fully autonomous car in the next five years. However, when asked which company they trusted the most to develop safe autonomous car, 24% said Tesla. It was surprising that Tesla received the highest trust score (compared to Toyota’s 9% and General Motors’ 6%) despite the recent accidents in Texas and California. 

Both AAA’s and CarGurus’ surveys had paradoxical results. 55% of the respondents in AAA’s survey said they want semi-autonomous features in their next car, despite the opposition to the technology. Car Gurus also found that safety is the top reason people want autonomous driving (64%) and the top reason why they do not want it (81%). 

Because of the novelty of autonomous driving technology, it is subject to a much higher level of scrutiny. Hopefully, it is not enough to slow down what could be a very revolutionary technology. It is just going to take some time. 

The Safest Used Cars for Your Teen Driver

Safety is one of the biggest factors parents look for when they are buying their teenage driver’s first car. Given that the fatal accident rate for teenagers is three times that of all other drivers, the parents’ focus on safety is justifiable. Over the last ten years, more and more safety features have become required on car models. Anne McCartt, the Insurance Institute for Highway Safety’s senior vice president of research, states that “it is easier than ever to find a used vehicle with must-have safety features and decent crash test performance without spending a fortune.”

The Insurance Institute for Highway Safety is guided by four main principles when defining safety in their recommendations:

  • Young drivers should stay away from high horsepower.
  • Bigger, heavier vehicles are safer than smaller cars
  • Electronic stability control (ESC) is a must.
  • Vehicles should have the best safety ratings possible.

The IIHS recommended list of used cars are all under $20,000 for base models, with many choices under $10,000, and even a few as low as $5,000. According to an IIHS survey, average price paid for cars driven by teenagers is $9,800 and the median price is $5,300. McCartt however urges parents to consider paying a little more for safety if they can.

GM Moves to 3D Printing for Refined Part Designs

General Motors and Autodesk have recently collaborated to create new part designs that will become a reality through 3D printing. These new parts will serve every purpose and, more importantly, be lighter and stronger than traditionally manufactured parts. David Darovitz, GM’s global product development spokesperson, spoke about the seat bracket design in particular stating, “We developed a proof-of-concept seat bracket that transitions eight components into one using new generative design software from Autodesk. The concept part is about 40 percent lighter and 20 percent stronger than the bracket we use today.”

Smaller components such as seat brackets are not the only application for the 3D printing technology. The first recipients of the 3D printed parts will be on low-volume vehicles. But why would GM restrict this technology to low-volume vehicles instead of using it to differentiate themselves from their competition, especially those in Detroit? Darovitz explains that, with a part like the seat bracket, a cost analysis must be done from a total enterprise cost perspective.The new design will eliminate the shipping cost of sending the parts between suppliers, the capital cost of building stamping dyes for each of the stamped parts, and the welding costs. However, 3D printing costs are still high compared to those of traditional manufacturing method, which offsets the savings listed above.

Because each part is different, an individual business case analysis has to be made to determine whether or not the costs of 3D printing that part are lower than traditional manufacturing methods. “We may choose to invest more to 3D print a part if the added value in terms of performance merits the additional cost,” says Darovitz. “If a traditional manufacturing process is less expensive than 3D printing and there is not substantial performance benefit, then traditional manufacturing processes will be used.”

We see 3D printing on  more low production applications, but that doesn’t mean it won’t be seen in the high-volume vehicles that GM produces. “As the capabilities of 3D printing advances to print larger parts faster, the technology will be able to support higher-volume end-use production applications,” Darovitz added. “This will enable us to broaden our use of generative design for additive manufacturing across the GM portfolio to further lighten our vehicles.”

Even though the manufacture of vehicles using 3D printed parts is still a pipe dream, it is on the way, but there is no definite timeline. Darovitz states,”We are working on part designs now for future application, but not ready to share the specifics.”
