"Many studies and observers cite the rise of mobile devices and their growing role in our lives as a possible cause behind the recent spike in traffic fatalities."

Anecdotally, in my area, teens often receive the current family car (which is often 8+ years old), or one of the families secondary vehicles. Then another vehicle is purchased for the parents, often new or a recent used vehicle. So the vehicle with less up-to-date safety options goes to the family member that is the least experienced driver.
