Question about Medisana Mc825

The massage mat is absolutely unsuitable for use in the car. I bought it to get a massage while gaming on the PC. If you slide back and forth a little on the mat, these "nipples" press quite a bit into your back, which makes it pretty useless for gaming. Now imagine you're sitting in the car and these nipples are pressing into your back. First of all, that's not pleasant, and secondly, it's probably dangerous if you're constantly distracted by the thing. My conclusion: Absolutely useless for the car and definitely illegal.

I don't think this massage seat cover is allowed in the car. And I can't imagine that you can tie the cushion to the driver's seat. It's still quite big and you'd almost have to lie down in the car so that the neck massage buttons don't push you forwards. When I sit on it, I can relax and not drive at the same time.
