I think this is why the Users Group meetings usually request multiple examples to back up the arguments. It's easy to dismiss one example, but three or four consistent examples are harder to disprove. These are great points though. I'll try and make notes on a few.
This, I think, is the best example I can point to of why I think it's linear: this is a step-by-step/cause-and-effect relationship. He's just not vocalising it as an 'I can do this and then do this', he just does it. Essentially, his thinking is a kind of 'I can't get anywhere because of the cop. But if I get this guy to speed up, he'll get the cop out of the way and we can go on.' Which is very linear.
She, however, doesn't understand the logic of slowing down. And it's only when he does it that she pieces it together. Which, depending on whether the guy is linear or holistic, is a pretty clear indicator that she will be the opposite.
I think her efforts to define the problem are way more holistic. I haven't seen the movie, but her line of "We can't go 55, it'll blow the whole equation" leads me to believe that she's trying not to upset the balance of things (it sounds like she's already calculated the route and speed). And when it becomes clear that they won't be able to keep going at that speed, she starts looking at everything else to maintain the balance she created: hence, trying to calculate what speed they'll have to go and at what distance, dependent on whether or not the cop takes the other road, etc.
Does he, though? If he's trying to fulfill anybody's needs, it's his own or the girl's. All he really wants is to get to the front of the line. He's not thinking about the cop's needs. He barely even focuses on the cop, actually. Only really at the beginning before the jerk turns up.
Again, I'd say it's the girl that's trying to hold everything together. She's the one trying to figure out how to ensure they don't slow down and 'ruin the equation'.
They could arrive at the same solution, but their methods of getting to it would be WAY different. There's a great post on this very site that illustrates how a Holistic assassin would work, as opposed to the commonly-understood linear assassin (which is basically just 'I find the target and kill them'). Essentially, they have different ways of handling situations. Whichever one works better for the given situation depends on the situation (and the author, naturally).
