Interesting concept.

wonder how steady it could be?

Neat idea, but yeah how on earth can this be that stable?

Probably isn't. <lauging>
Hey, I just report this stuff!

Ya' know, all my years in track and race cars, I seldom did an in-car. Too much hassle for some insipid video for me.

I don't think it's intended for track use. I doubt many track managers would let that pass tech unless there were a way to secure it. This thing looks like it just slips over the seat.

Might be good for parades, parade laps, or some road tours, but there's no way I think it would work effectively for autocross or track.

I'll keep my IO Port.
