Has anyone figured out what all the symbols are in the online lobby? I've sussed a few but others I can't work out. There's a little red wheel in one core et which shows the user is currently racing, There's a little turquoise circle with a + in it which I assume means a modified car? Then there's the circle on left next to speaker symbol, so far I have seen this in white, green, yello and red, any ideas? I thought connection speed maybe?
