At a time when federal officials are scrutinizing the safety of Tesla Autopilot, new research sheds light on how the system is reshaping driver behavior.
When the driver-assist system is enabled, Tesla drivers' eyes stray from the road more frequently and for longer periods of time compared with manual driving, according to researchers from the Massachusetts Institute of Technology.
This is believed to be the first study that uses real-world driving data to measure how attentive Autopilot drivers are behind the wheel, and where they're glancing besides the road ahead.
"This is the first time we can quantify the effects of automation, in this case specifically Tesla Autopilot, on how drivers pay attention," said Pnina Gershon, MIT research scientist and one of the study's authors. "Essentially what it shows is when Autopilot is engaged, we see glances off the road that are longer."
The findings arrive as NHTSA investigat…
