The indications the server gives are a bit suspect now and then. I have seen red connections driving without a hitch and reporting 35 ms ping. But I've also seen green connections ping ponging over the screen. Ping measurements seem fishy as well. GTS reported 12ms for one laggy Argentinian driver, and just now 7ms ping for a 3 bar Brazilian. That's not even beating the laws of physics, that's completely ignoring them. It's minimum10ms round trip through 1000 km of fibre cable. Suppose the server is in Miami, to the closest city in Brazil, Boa Vista, 3200 km, 32ms minimum ping through a straight fibre cable without any hops. In reality, Brasilia to Miami is 172ms round trip.
I wouldn't rely on anything the GTS server reports :/
That's not the point though. You're used to driving with laggy connections, EMEA is used to driving with much less lag. So you do have a slight lag advantage driving on the EMEA servers.
You maybe be physcially closer to the EMEA server, but all the regulars on the EMEA server are still at least at half the distance.
But ehh, give them Europeans a taste of what we have to deal with on a daily basis
