What about Exalted? I haven't mentioned it much, since I haven't actually played it; but the stunting system is not only a form of shared narrative control, it's reportedly one of the most popular parts of the game.
I've run Wushu countless times, and I've never once had this problem.
He doesn't have to. This is a lucky shot. The called shot part is mechanics, not fluff.
First of all: Exalted is NOT a 'shared Narrative Game' by any stretch of the definition. If anything the Forge, which you mentioned earlier, was a REACTION to White Wolf's very strong emphasis on GM narrative control. AT BEST Exalted rewards players who step up to 'narrate' their own actions by provided a few bonus dice to tests if it's well described.
If anything, white wolf products would be the antithesis of what you are apparently trying to force us to assume is the standard (the old, you have all been doing it wrong technique...)
And you apparently play with people who share your mindset. That does not mean that the 'rest of RPGdom' shares your outlook. Look, if I really wanted I could find a group of people that though crap was a useful sex aid. THe fact that everyone in the group thinks that crap is a useful sex aide does not make it a standard behavior.
While liking Wushu's shared narrative is in no what similar to crap=teh sexah, my original model train analogy just wouldn't go the distance. It remains that just because you and a few other people like something it isn't the case that it must necessarily be 'the right way', no more than mochachino icecream is better than chocolate or vanilla, despite being a popular flavor with a certain crowd.
As for the last bit: your constant hand-waving away things that 'break' your example is tiresome. I've tried at least once to convince you that making a logical rational argument should resemble, on some level, the art of making a new scientific theory. You make your theory and then you submit it to tests and trials. If and when it fails those trials, you can not just ignore them, you must alter your theory, or discard it, to account for those failings.
You have an end result you want, and you are constantly rejecting anything that hurts your end state. This is the opposite of the 'scientific' method, which really should have a more generic term like 'rational method' or something.
Let me go over the counter arguments again, some of the flaws if you will with your arguments:
First of all, the entire 'bypassing armor' requires approval from the GM. Regardless of how you feel about GM fiats, this is not an 'arbitrary' call, it is specifically called for in the rules. You yourself have stated that your entire example hinged upon the 'in game' rational of there being an open hatch of some sort, even if it requires a miraculous ricochet. The DEVS have stated that the miraculous ricochet is a feature they intended to have for longshots and high edge.
Second, you are, by your own admission, not actually attacking the Citymaster at all, but the driver. Therefore, from the get go, your entire name is a bit of propaganda, a false statement designed to make it look worse than it is.
Following this train of thought you are attacking the driver (a passenger, in a sense). As in any case (what is the weather like, what sort of lighting is there) the GM makes a call about how much cover is provided. You can not allow the GM to make one call (weather) without expecting it to be perfectly valid for him to make another call (total cover). If you DON'T allow that sort of call at all, then you are playing so far from the norm for shadowrun that it's worthless to talk about how the rules interact with your playstyle. They aren't designed around those assumptions. Analogy: Its like complaining your Ford Festiva is a terrible ship. While it may have many characteristics of a ship (made of metal, a vehicle, carries passengers and cargo) it is not, at the end of the day, a ship.
Since the Citymaster, reasonably enough, provides 'Total cover' the passenger must be attacked as if through a barrier. While you refuse to acknowledge that, it doesn't change the fact that the rules make that case. This further invalidates your case in that you can't suddenly bypass the armor of the citymaster, making your longshot test essentially worthless. While you certainly CAN bypass the armor of the citymaster, it means that the citymaster, not the pilot, makes the body test to resist damage, something it can quite easily do with it's 16 body.
Third: It has been revealed on close examination that you have not been accounting for the defense tests in any real manner. This is a particularly obnoxious oversight given the fact that one disadvantage of any longshot test is that you are perforce working with a limited dice pool. When a vehicle is attacked the pilot makes a defense check. When a vehicle is attacked you can either attack the vehicle or the passengers. These are not mutually exclusive situations, as you seem to be claiming. In fact, arguably, attacking the pilot gives him TWO defense tests, one for the vehicle (if the vehicle is attacked...) and one for himself (the passenger may make a dodge test at -2 dice pool), though you blithely assumed that the pilot was a rigger, which meant you longshot test would almost certainly be countered simply by the driver swerving away gracefully.
You have also blithly assumed that you could bypass the passenger's armor as part of bypassing the vehicle's armor. Doing so with a 'blind shot' calling on top of things to boot. Interesting. I, for one, would say at a minimum that that would be two, seperate, called shots. However, as you only get one free action, you could only do one or the other. Not that it matters much if the target ISN"T in total cover (they don't get the vehicle armor then, they get a cover bonus to defense), then you can safely ignore the armor of the citymaster to no penalty.
In fact, you entire case rests on a series of increasingly improbable assumptions about what is allowable, simply by virtue of an explicite ruling saying that you can not. For example, there is no explicit rule that says you can't make a called shot if the target is obscured by 'total cover'. On the other hand the Called Shot rule doesn't explicitly allow you to make one whenever, and however you want. Funny thing, that. As I like to say, what is good for the goose is GREAT for the gander. Of course, the Called Shot rule explicitly allows a GM to decide what can and can't be a called shot.
There is no shoddy rules here, only shoddy reading of the rules.
At the end of the day, the biggest crime committed by the 'Knifing a Citymaster' is assuming that relying on a few common sense calls, in a game built around the assumption that common sense calls must be made, is bad.
Which is funny, since most of the 'shared narrative GM is bad' stuff I've read suggests that players veto actions that don't make sense, and I'm pretty sure that most sensible players, even without a GM, would agree that these are bad calls and would make them anyway. Allowing someone to casually, blindly, knife, or even shoot, the pilot of an armored vehicle with all those assumptions is what ruins the fun for a lot of people.
Of course, I can only slightly facetiously point out that by using your chain of 'logic' as demonstrated in this one example, its perfectly permissable to shoot someone with a knife. After all I'm sure saying 'its only a melee weapon' is a GM Fiat, the rules don't explicitly state you CAN"T shoot knives. They must be broken then.
