Long-Term Exposure to ADAS: Everything You Need to Know

by Gwen Newell

Sophisticated driving assistance systems are now common in newer vehicles, but when it comes to new vehicle technology, practice doesn’t always make perfect. New AAA research shows drivers’ confidence and understanding of the technology varies dramatically based on whether the drivers received formal instruction or decided to learn as they go.

AAA Foundation for Traffic Safety’s new research zeroed in on adaptive cruise control and how drivers’ understanding and use of the technology changed during the first six months of ownership. ACC assists with acceleration and braking to maintain a driver-selected gap between driver’s vehicle and the vehicle ahead of it – and research about this particular technology suggests that trial and error learning only gets a driver but so far.

The study found that during the first six months of new vehicle ownership, many drivers demonstrated an improved understanding of the ACC system’s limitations and despite learning more about ACC through regular use, drivers failed to achieve the same level of understanding when compared to another group of drivers that received short but extensive instruction on the system. Furthermore, a potentially dangerous sub-group of over-confident drivers emerged who failed to grasp ACC, yet were highly self-assured in their knowledge – this development demands future study. Research also shows that a “learn as you go” approach still leaves gaps in understanding when compared to another group of drivers who had a very strong grasp of the technology, partially due to a brief intensive hands-on training session.

AAA recommends that new vehicle owners follow this PLAN:

  • Purpose: learn the purpose of driving assistance technology by requesting hands-on training at the dealership, reading the vehicle’s owner’s manual and visiting the manufacturer’s website.
  • Limitations: do not make any assumptions about what the technology can and cannot do. A driving assistance system should not be confused with a self-driving one.
  • Allow time for practice: allow time for safe on-road practice so drivers know exactly how this technology works in real driving situations
  • Never rely on it: do not rely on this technology; instead, act as if the vehicle does not have it with the driver always prepared to retake control if needed.

AAA also recommends that researchers, automakers, and government agencies work together to better understand driver performance, behavior, and interactions in vehicles with advanced technologies.
