There is so much with this "keyless" technology that disrupts my long-entrenched rhythm. I've almost walked away and left the darn thing running 2-3 times in the past 6 months, and actually did it in the Walmart parking lot last week. I came back from shopping and my car was running!!! I don't have a key to turn and pull out of the ignition, and I've yet to develop a replacement habit. That's only happened once, thank goodness. I guess it's a testament to how quiet the engines are.
Same goes for locking it myself...the key/fob is not already in my hand to push because it never leaves my pocket. Part of this is my being retired, so I'm not in a routine and I'm not in the car to & from work every day to form those habits...in fact, I don't drive every day.
I still have my truck. Sometimes I must look like a spaz when I get ready to exit my CX-5 because I reach for a column shift that is not there to put it in Park and my left foot automatically goes to apply the imaginary parking brake. It was the same way when I had my manual transmission Volvo & I would switch between it and my truck. I KNOW my truck doesn't have a clutch, but there goes that left foot when I pull to a stop. At least I stopped reaching for radio buttons that aren't there in my CX-5. This keyless thing is a whole different variation.
