IP, perhaps I should have used a better analogy. I initially used the speed gun because it was a simpler, more straightforward example.
A more accurate example is line calling in tennis and its conversion from entirely human action and judgment to full fledged electronic calls featuring a computer generated instant-replay review system used to call serves and settle challenges. I think my point is better suited to all the intended and unintended consequences it created. First, let me point out that line calling is a collaborative process in tennis. In case you don't know, linespeople each have their own line to call, but there are redundancies built in to protect against occasions when their vision might be blocked by a player or debris. If that happens, either the other linesman standing directly opposite on the same line can make the call, or the chair umpire can step in and either make a call or order the point replayed. Before today's current replay system, such occasions, though rare, could be comical, especially if they happened on clay where opinion of what is in or out can be virtually subjective and can involve multiple people, from the linesman, to the umpire, to player, to event the tournament referee as the final arbiter. Most linespeople are also not a usually a professional core who work for the international governing body rather than their federation or local organizer. They tend to be local volunteers at most tournaments who are active in the community tennis association, where they frequently perform the same service at challenger, junior and amateur age group tournaments. So at even big events like the US Open, while some linesmen are employees of the ITF, most are volunteers with the USTA and are American. Claims of home cooking with linesmen have always been a part of tennis. That's why the ultimate arbiter, the chair umpire, is barred from being from the same country as either of the players in the match he is calling.
As far as electronic systems go, let me point out that the debate over various forms of electronic line calling in tennis has been going on for several decades now. It basically started at Wimbledon 1980 when the Cyclops service line calling system was introduced. It would issue a high pitched beep if the serve landed outside the service box and would remain silent otherwise. It was highly controversial because initially it's ruling was the default and the service line judge (who was still on the court) acted first as just the operator of the equipment and only gave his/her own call if it malfunctioned. The relegation of a human's judgment below that of a machine was a major affront to many purists back then. Of course, the technology never worked very well and broke down often. But it remained in use for more than 20 years until it was replaced with the current and far more accurate system.
The next major change was the elimination of the net judge, who used his finger on the net cord and his vision and hearing to determine if serves touched the net before landing in the court. If so, the serve doesn't count and must be repeated. Today, that is all done by an IBM-made electronic cable affixed to the net cord that sends a signal to the chair umpire's computer and issues a beep if a let happens. The problem with it is that it is so hypersensitive, that it frequently calls lets that no human could possibly sense, thus giving the impression that it may be malfunctioning. In other cases, some other outside object, perhaps an insect, may set off the device. The problem when that occurs is the the rules as written don't allow the chair up discretion to overrule the device. So even if the error is obvious, the serve must still be repeated.
Today, line calling for all parts of the court is done by humans and verified by a system called Hawk-Eye. It uses cameras mounted at multiple angles around the court to created a 3D replication image of the court. It is integrated with the speed gun and records official records of where each ball struck during the match lands to within (IIRC) 2mm. Created in the early part of the 2000s, it was a just curiosity for fans and players alike, initially only used by the TV networks to enhance their own replays of calls. During that early period however, everyone knew the commentators had it and suggestions began to be made to make use of it on tight calls. Sometimes players would even shout or signal up to the booth to request unofficial verification of the call from the announcers. In some cases at the biggest events, the TV feed would even be shown on the jumbotron on the court so that everyone (fans, players, officials) could see that some calls were blatantly incorrect. Yet up to that point, nothing could be done to correct the mistake, despite the visual evidence. That was the case until the 2004 US Open women's quarterfinal between Serena Williams and Jennifer Capriati forced its introduction as an official line calling tool (sort of our SLC 2002 or Athens 2004).
It was a night match (which can impair vision for players and officials alike) and the various linesmen made several incredibly poor calls which all went against Serena (in that case she did not melt down btw). The chair umpire even intervened on two calls which tv audiences were able to see as inaccurate on normal speed instant replay without even needing a Hawk-eye replay. The calls were at significant enough points in the match that it was more than arguable that they affected the outcome. After that, the tide changed and consensus grew quickly that Hawk-Eye's time had come. A period of official testing of the equipment ensued over the next year and it was finally and gradually introduced at smaller tournaments in 2006 with players give a set limit of incorrect challenges they could make in each set played. Eventually it made its debut at a major near the end of that season at the US Open. Wimbledon and the Aussie Open followed suit the next year.
Like our current replay system in skating, Hawk-eye sees things we had never tried to see before and has actually changed the way the sport is played. It's taken power away from human judgement (at the behest of the player in the form of a challenge to the original call) and infused an air of infallibility into a very complicated camera and software system that is dependent of adequate light, sufficient numbers of camera positions, etc. to be fully accurate. Still there are occasions when human judgment from the unseen system operator high above the court and not a linesman or umpire has been used to determine a call. That usually happens when the jumbotron or broadcast display fails. The internal system itself is still working, but unseen by the players and spectators. In that case the system operator radios the call down to the chair umpire who is bound to accept and impose it. Such a situation, could certainly be one where suspicion of undue influence could occur. Another problem is that the technology is still very expensive and is not available at all tournaments. Even where it is used, it's usually only on the TV courts rather than all those used in play. Even at the majors. That presents an unlevel playing field for lower ranked players who are not on show courts or big events very often and will therefore be less experienced in correctly choosing the best times to challenge calls.
Ironically, stats have shown that the vast majority of the time, the linespeople get the call right and the players get it wrong, yet their authority has been diminished by the same system that is validating them.
So as you can see, line calling in tennis is just as convoluted at times as judging in skating. Human error, excessive reliance on technology, possibility of bias, etc. all play a role.
In the end technology is playing an increasingly large role in all sports. They are all struggling with how best to use it while also maintaining some aspect of the human element in how they are conducted/overseen. So far an ideal solution has yet to be found.
