I just saw a video on this and it seems pretty obvious that these are fake. Unless you use one of those weights or your hand is perfectly resting on the wheel it'll start beeping at you about a minute after you let go and completely stop the car in less than 2. No way to drive a significant distance like that.
I wonder why actual news outlets are reporting this as real? It fooled me, as evidenced by my previous comments, but now I realize it’s not even possible and that these videos are fake.
