I think you're dead on when you mentioned going 90 mph seems right to you but maybe you're out of sync with the rest of the world. That's a major battle for me. It feels so normal to me to zoom along, most of the time I don't even notice until I start to get really irritable with everyone and it seems like I'm surrounded by people whose whole purpose in the universe is to get in my lane and slow me down. Irritability is my biggest clue that a mixed state is upon me.
