Push-button cars cause deaths in the US
Surely you've heard of new cars that do not need a key to start the engine, just press a button. But what many do not know, is that this convenience can be a risk to drivers who have this type of vehicle.In these cars, the driver can leave the "smart key" in his pocket or even on the console, because the key emits a radio signal that allows you to open the doors and start the car only by proximity. According to a survey by The New York Times in the United States, at least 28 deaths and 45 injuries are related to drivers who left the car unknowingly and suffered carbon monoxide poisoning.That's what happened to Fred Schaub, 75, who parked his Toyota RAV4 in the garage and entered the house with the "smart key." The car's engine was still on because the driver was nearby. And after 29 hours, he was found dead while his house had a carbon monoxide concentration 30 times above that tolerated.Also in 2011, a group of automotive engineers recommended the installation of audible warnings if the vehicle's doors are closed and the engine is running. Some manufacturers have followed the recommendation and have scheduled the car to turn itself off after 30 minutes stopped, but others have not yet made changes.There is still no legislation requiring automakers to apply this measure, even in the USA.
