If you're pounding one out that won't really save you. He probably games with headphones and just doesn't want to get jump scares by mom.
I always had a desk and a bed and I made a point to never have my back towards the door when I was at my desk for the above reason.
There's a happy medium. I have a slightly newer VW GTI (2017) with a touchscreen but there are still buttons and dials for basically everything. It's a perfect infotainment system if you ask me :)
