80 isn't an adrenaline rush for a granny even on a city downhill. I going with the covering for him crowd. Doped out of his mind. That or he just doesn't G-A-S about the safety of others on the road.I would struggle with such an idea as intentional loss of control. Intentionally speeding to try to get a cheap thrill I could buy. Tiger strikes me as the personality type that enjoys an adrenaline rush.
