This has nothing to do with retractable door handles, it has to do with the fact they are electronic and not mechanical. Even though the car should have unlocked and extended, if the crash was severe enough the power will be out and that won't happen. Many other cars now have electronic door releases, and this issue affects all of them. Also, even cars with mechanical door handle now auto-lock for safety, and if the car didn't unlock you'd have exactly the same issue. It needs to be standard operating procedure: if the door handle does not work, break a window and use inside latch to open the door.
Yes but from the inside its mechanical and can be opened by the driver or through the window.
