My home system is fantastic, I am comfortable, and drive a nice car, but you can get a great system in a family sedan as an upgrade these days.
It was purely a comment about state of mind. When I am in the car, it is just me, the other cars, and my music. There is no computer drawing me to do some extra work to keep the company going, no treadmill telling me my butt should be smaller, nothing that needs to be cleaned or washed, no food to make, and I rarely make or answer calls in my car. It's my "safe space" :-)
