This is how one commuter does it, Say what you want, he can ride.
I recon he is pretty sharp to be doing this, I don't condone it but he is alive because he has very good reactions.
You may want to make sure you are seated before watching. The last 3 mins are where its at.

I do filter, but prefer the odds to be (much more) in my favour !
