I don't think any car keyless ignition requires the key to be present to continue running. You don't want a car to shut off on the highway if someone drops the key behind a metal object or the battery dies. If you start a car, and then take the key out of the vehicle, you will get a message like this: https://i.ytimg.com/vi/Jo6gzVfAElc/maxresdefault.jpg https://i.ytimg.com/vi/Jo6gzVfAElc/maxresdefault.jpg You will be able to drive the vehicle until it is put into park or shut off, and you won't be able to drive it again until the key is present again. This has stranded some people who have done the following: * start the car * get out for some reason * leave the key by accident * get back in the car and drive away * park at their destination * they are now stranded without a key

Even more surprising: fobs that don't work if the key is in the ignition. My 1996 Mustang had a bad battery, so it would barely start. I took the remote fob off the key ring and left the car running, but locked it (using the physical door-lock button). When I came back later, the fob would not open the door. WTF? Had to have another key brought from home. Another good one: If you open the back door of a Mini Clubman (or the regular Cooper, most likely) and then accidentally drop your fob into the car and close the rear doors or hatch... the car will re-lock itself and you're fucked. This is great when it's a hot day and you just put a dog in the car, which is in the sun. Now you get to break a window. Yay German engineering.

My car beeps whenever the key is not detected in the cabin while the vehicle is running. It would be very hard to leave the key behind by accident.

  My experience is the same. I suspect one would have to really not pay attention to manage to do this. e.g: stereo up, car already dinging for other reasons, absent minded driver, etc.
