The rise of the remote car fob has proven deadly as drivers un-learn the habit of turning off their engines by turning a key.
Since 2006, over 2 dozen people in the US have been killed by carbon monoxide when their keyless ignition vehicles were left running in the garage. 17 million such vehicles are sold each year in the US, but inexpensive software fixes to warn drivers have faced resistance.
Proposed regulations to warn drivers when the cars are left running have stalled amid auto industry pressure. For now, it’s up to carmakers to voluntarily incorporate warning features—and uptake has been uneven.
