Research from the University of Iowa finds that even a simple conversation creates an "attention disengagement" lag that affects a driver’s reaction time.
Study Finds Benefits of Plug-in Vehicles Depend on Battery Size
PITTSBURGH — According to a new study from Carnegie Mellon University, plug-in vehicles with small battery packs and hybrid electric vehicles (HEVs) that don't plug in can reduce life cycle impacts from air emissions and enhance oil security at low or no additional cost over a lifetime. But plug-in vehicles with large battery packs are more costly and may have higher or lower emissions than HEVs, depending on where and when they are plugged in.
