It's gonna be a long one, this. Anyway here we go
Going into the UK region at first I only had two goals: To have an account where I can race with relaxation (DR S is very stressful) and so that I can meet some of you GTP people around in Sport Mode. That didn't last long at all since I noticed my exponential progress there and so I revised my goal to get DR S there and then move to the US to do the same. Right now I have 2 more objectives added into the original goal as well (Snitch Top 1 in every region, as well as win an FIA race in each of them) so yeah, those are my current views on why I made three accounts.
Playing on 3 different regions can be done healthily if you don't mind the FIA races. On the UK the timeslots in my region is 1-4AM in the morning, and in the US 6-10AM.
Now my thoughts on the racing environment per region. Like
@inri said, the race environment between Asia and Europe is not all that different, really. Sometimes you'll see different cars on the leaderboards if the meta game allows it, and if it does I notice that the Asia region players tend to go for more agile cars, even if they're not as powerful on the straights (like inri's toyota 86 example). Both regions are very clean (trust me they are). But their race pace at different ranks are a whole lot different. Asian players are relatively skilled for their rankings (DR B Asian is as good as a low A European) until at around DR A. At DR A in Europe the difficulty level shots up exponentially, because there you start seeing people from the famous racing teams (TX3, TRL, etc.). My personal take on this is that because of the lack of organized racing teams in Asia, they lack the practice done by the professional teams and so get left out at the higher rankings. But for sone weird reason that I do not know, if they are pitted against other drivers that aren't in a racing team and is around the same ranking as them, the Asia players would probably come out on top.
The US of A deserves its own paragraph... and all for the wrong reasons (I'm sorry US peeps

). This region is unique to the other two in the sense that you can't compare both their etiquette and skill level to the other regions at all. It's the dirtiest of the three. It's so dirty that in almost every race there's always a rammer, divebomber, you name it. I'm very lucky really that I see all this carnage only on my rear view mirror. Even on the cleaner tracks (Kyoto Yamagiwa) it's common to see 3-5 people with a red SR rating. I don't know the experiences of other people but on the other regions at high rank red SRs are only given to a couple of people there. One day I was unfortunate enough to spin on a race, relegating me to the midfield.
It was hell. Starting from the back at Europe and working my way up (at low ranks, even) is 10 times cleaner than a high rank midfield in the US.
Their skill level. Their Top 1-3 on the leaderboards (mostly Snow, anthalicious, and another ORMA) are at par with the other regions, if not the best. But look further down and... 4th usually has a 5/10ths second gap from 3rd, and most probably is 2-3/10ths off the pace from the Top 10 leaderboards elsewhere. Needless to say it's quite easy to get a Top 10 leaderboard there and make it stick. Granted anthalicious advised me to hold my judgement until I'm at DR S at the US, and that the different timezones may play a role (not sure about the latter, though. I know that the US is 12 hours behind my timezone, and I play until 2AM, which is 2PM on their timeline, so I do think that I get a taste of the racing there at prime time, especially during weekends), but so far that's my judgement on the US region
I care
