I thought the same thing about the bike laid down in front of him. Definitely too close!
I can't say that I'm 100% perfect on the speeding bit (I usually go with he flow of the fast lane on the highway ~80mph).
That said, I also treat every car like they're trying to kill me. I think of the dumbest thing they could possibly do and what I would do to avoid that situation. That has saved me more than once. ABS brakes also helps for incredibly quick and safe panic stops.
