Everything can be said to be "sophisticated gambling." Nothing is certain, and only those who don't understand finance believe that any financial instrument whatsoever is a certainty. And even outside finance: the job you took isn't certain, nor is the car you bought or the marriage you entered into. Finance has its problems but the gambling aspect isn't the root of it.
A local business or gov't entity got breached, possibly an insider, and due to living there now or in the past has local knowledge of popular roads that 80% of their targets would be familiar with. Or if they didn't live there it'd be pretty easy to use public records to see where traffic tickets are given out most, where traffic cams are installed, etc.
This kind of thing isn't new though. The Internet is just the latest means of communication with the public. Public opinion has, and still is, manipulated for good and bad via mass media, grassroots campaigning, bribery, agent provocateurs, etc., etc. Replace "internet" with "telephone" or "printing press" and your post would read the same. Governments always want to control their "internal political processes" and to achieve that they tend to block out anything that interferes, whether it be foreign governments or internal factions that run counter to their interests.
