Sounds cool, but I'd rather not be 'tagged' with a rating from other people, as well as have 'requirements' for ratings on servers. Because the fact of the matter is, this is all rated based on opinionated users, and face it, not everyone out there are experts in judging people's actions in racing. There are always many different perspectives when it comes to rating a driver who is (or isn't) really a "5-star driver", or what ever you may call it.
If you are looking to rate someone simply with a 'good' and 'bad' rating system, it may be misused in ways that could be impartial I think. There are many drivers out there who classify good racing in many different ways. For example, uber clean racing where no drivers EVER touch each other and race like old posh gentleman every corner... they'd call that a good scrap. However, others find a little door-to-door banging a good hard fight, as long as it is safe and unintentional.... while the latter group would say that it is dirty driving I bet.
Every driver also makes mistakes, and likely do not do things intentionally for the betterment of their racing. That said, a rating system could not be fair in this manner too, because people may not be fair in deciding who was at fault.
You can only really base a ratings system on obvious and blatant poor racing behavior that is not tolerated on virtually any server we know of in LFS (eg. Wrecking & rough driving, cheating, bad language, etc), . THAT is one thing that LFS players do look out for in servers, because they know licensed servers should have cleaner racing than anywhere else. Although, like I said, there are players out there with pitchforks that really would just love to give someone a negative rating based on what they believe, or simply prior race encounters, or just have a grudge with them.
Also, for ratings to be truthful and fair, you'd need to do voting and reviews from every driver that raced he or she. Much like a Wreckers Barricade sort of deal, with proper replay review of an incident. Else the ratings will just be like a lightning round, and not thought through carefully.
Sure... it's rather complex the way I am making it up to be... but I can only imagine users bumping up someone's rating for good measure, when in fact they are not a good racer at all.... and vice versa for a user's negative score. The last thing I want is to feel unwelcome in a server because of a rating that is most likely unreasonable... and be hounded by so-called-elitists who 'have' a higher rating than I do.
I understand a reason for having a rating system, such that you want people to gain a better score based on improving their appropriate behavior when they are on a server... it just seems nonsensical to me, especially in the online gaming world where arguments flare up, and ratings are not always accurate.
