Seriously? Every vehicle, every person, is captured on some camera or another every hour of every day, so long as they're moving through anything that isn't a Z-zone. The issue is, and for the most part in SR the issue has always been, the sheer amount of data the people have to plow through in order to get your ass. So it comes down to whether or not the corporation is able to a) get the data, b) sift through the massive amounts of data, and c) care enough to do A and B. GridGuide isn't owned by Knight Errant, and though they undoubtedly have a 'pursuit of suspect' agreement, there's still going to be a metric ton of stuff to go through.
For the most part, though, I tend to think that unless you committed some brutal crime or another, so long as you were professional about everything, there's only so far that the corp you hit is going to go - whether willing to go, or able to go, because GridGuide &c. isn't going to just fork information over for the asking. Information is valuable, after all, and is catching your ass within the 3 days it's going to take you to unload the stuff you got going to be worth the cost of catching you? The 20¥ per request for the data from GridGuide, and after all, backtracking someone is going to take a lot more than two or three requests? Etc. etc. And if it isn't Knight Errant after your sorry (truck), then so long as you got off that corp's property, the truck is probably free and clear.
For a corporation, catching a shadowrunning team is all about the bottom line. Will it be better for their bottom line in the long run to hunt down and blow your team away, or would it be more expensive to do so? Your job is to make it simply not worthwhile to find and frag your bod, whether by making it incredibly difficult to do, or by making the materiel expenditures and death benefits for the kill teams sent after you far too expensive.
