Wow, I like it. It seems like the approach is, "we have no clue what exactly is it about cars that works this way, so let's replicate as much of the experience as possible". Brute-forcing the problem, but sounds like it could work well.

A friend of mine (another crazy tinkerer, which is how we got to know each other) built something like that in the 90's for one of his children that could not sleep anywhere but in the car. It was a crazy contraption but it did work.
