That's a good point to make Gou, but what are you driving at?
Are you saying to be open minded about actual conflicts and not to try and go about them in a pre-defined way, or are you saying that martial arts training isn't ever really going to give anyone the upper hand because of the un-predicatbility of the situation?
I would hope, at least, that kenpo brings us closer to street situations that some martial arts do.
At our club we frequently try and do as realistic a training as possibly without actually sending people limping home (if you train full power and with brutality, then you're willfully subjecting yourself to the one thing that you're trianing to avoid), but I do realise that it's never going to be the same.
One thing that's quite interesting to do it set out some tables, sit down at one, and then have 2 or 3 people start on you. There's a tendancy to train in open halls, with no obstructions, then someone gets into a fight in a pub an the first thing that happens is someone pushes them backwards over a table! Try it, you can throw people into the tables yourself (Taming the Mace works well), whilst trying to avoid them yourself etc.. From a seated position, you can come up with lots of responses to grabs and things as well, including some particularly nice slam-their-face-into-the-wood ones
Another good exercise it to make everyone spar in one small corner of the room, instead of spreading out. Not only does this teach people to avoid 'civilians' as it were, but you can also try and lose the person who's actually attacking you by moving through the crowd. Good for peripheral vision and spacial awareness too.
Other favourites are someone trying to cut you up with a smashed bottle or glass (just cut a plastic bottle jagged, and then smooth off the pointy bits), 2-4 onto one sparring, and of course a technique line up with random attack met by random defense. You can also try starting on the floor and trying to get up, which is pretty scary.
Of course, lots of padwork is also essential, so people actually get used to slamming their fists, feet, elbows, knees at. into something more than thin air.
...as I said, it's never going to totally prepare people for one of more random nutters intent on damaging you, but, it's surely doing more good than standing in a neatly formed line practicing lock out punches and develping a lovely ki-ai nosie...

p.s. I think the guy in that video might've done better if he wasn't wearing that hoodie! It was covering his face half the time. Always remember if you're going out, what are you wearing and if you had to, can you fight in it...
As a side note, because I'm a student I have to walk everywhere with a heavy rucksack on, so one day I started training in normal clothes with the damn thing on my back...didn't half make a difference to mobility!
