Well, the standard rules are unrealistic at least in the sense that movement is chunky. Take an armored guy with MA 6. If the next cover is six hexes away, you have no shot at all. If it's seven hexes away, you have a shot with no penalty.

But that sort of crude outcome really can't easily be done away with. There's a tradeoff between simplicity and realism. I tend to think that there should be some chance at a shot when moving from cover to cover in one turn, but maybe it's not important enough for others. Partly depends on how often it comes up and I'm not sure it's come up at all for me.
