The National Highway Traffic Safety Administration (NHTSA) has vowed to mandate a new set of rules about how door handles work in all motor vehicles.

There have been numerous issues with people attempting to exit a vehicle after an accident, where the door handles did not work as expected.

The issue stems from the rise of electronic door handles, which can become compromised in an accident.

In our ever-increasing digital world, even seemingly simple items become electronic. Take, for example, the humble door handle. On lots of vehicles these days, that handle operates electronically instead of mechanically. And that can become a big problem if you're in an accident.

Automakers are required to have mechanical backup systems just for such scenarios. But they're often in odd places or difficult to find at all. The owners of a car with such a setup might not even know their car has mechanical backup door handles.
