What if someone leaves a keyed ignition car running in the garage? They're so quiet, you might not know it's running right? My Keyless Prius will emit some loud beeps if I get out with it "ON". If I get out of my keyed ignition F250 and walk away because I didn't know it was running while I was driving it, it does nothing to tell me it's still running and I've left the vehicle. I'm thinking about suing Ford because it doesn't tell me to shut it off before I walk away from it. How could the manufacturer be so negligent. Sarcasm intended.
