I drove this rental car and parked it inside my detached garage at 7:30 pm. i neglected to push the start/stop button upon exiting the car. consequently, the car continued to run. at 10:30 pm, needing a tool, i went back and opened the garage door. a rush of hot air hit me in the face. to my horror, i realized that i did not shut the car off. garage temperature had to be about 120 degrees. who knows what could have happened, had the car run all night. i think there's a simple easy inexpensive fix to this. solution:require all auto manufacturers, utilizing the keyless ignition option, to, mandatoraly, equip all vehicles with an automatic shut off if a car idles in park (transmission sellection) for more than 20 minutes. this safety option should not be able to be over ridden by customer. i'm just thankful that my garage was detached. carbon monoxide deaths via keyless ignition are easily avoidable.
