I'm not a massive fan of speeding, largely because of being forced into attempting an emergency stop at 75 mph once. Still have nightmares about that.
I'll occasionally switch off and find myself drifting into that kind of speed like everyone else but prefer to stick within the limits and keep my wits about me.
f**k knows what it feels like to have to hit the brakes while driving at 100 mph plus in an emergency but I'd be willing to bet that 90 percent of these c***s that drive at these kind of speeds would have no clue about how to carry this out safely.
