By: Gary S. Vasilash - February 25, 2019 at 7:17 AM

The issue of electric vehicles is one that is perhaps of equal concern to OEMs and suppliers as autonomy, with the difference being that while autonomy is something that is still being developed (yes, there are a multitude of “advanced driver assistance systems,” short of Waymo running Pacificas in Arizona or Voyage running a test fleet of minivans at The Villages in Florida, there are still safety drivers and engineers rolling around on public roads in vehicles), there is a growing number of EVs out there and a whole lot more to come.
