What should be done?
Reprogramming vehicles is something high tech auto repair shops like Dolson Auto can perform if the manufacturer released an update to protect people from an inadvertently idling car or truck. Hybrid electric vehicles are especially dangerous because they can sound as if they are off when in fact their engine could restart any moment.
The car company should issue updated software to shut the engine down under a number of existing inputs it already monitors. Some of this could be no activity of vehicle controls for more than 10 minutes, key fob out of range shut down, seat sensor detects no driver, or seat belt unplugged for more than a minute. Many possibilities are right there with simple software updates. Many lives could be saved.
