Well... not really defending or attacking any party, but as what Scawen did say, there is really intense online racing.
The things is, how restricted you are thinking of racing? Do you want the racing must be done originally way, old school, without any insims, or do you like to have the other extreme? With absolutely all customized things from insim to layouts, with various possibilities, yet still very close racing with more than 3 cars under 1 second on finish line.
I am sure you have not even tried yet or even looked at it. Do not trust the headlines or any other people, find out yourself of it. The thing is, people are less online due the other sims/games/life/other stuff, but it still happens what you want for. It is just in specific time.
Give an another shot. As what vitaly_m did say, there is league racing with appropriate stuff in specific times.
And now similar thing in finnish ( trust me, it says same thing! ):
Niin, sitä kovaa ja mukavaa kilvanajoa tapahtuu kyllä, mutta tiettyyn aikaan, koska porukkaa ei ole enää ihan sellaisilla määrin, mitä ennen. Mutta kyllä sitä löytyy.
Katso seuraavalla kerralla paremmin. Mutta toki, jos edelleen tuntuu siltä, että ei sitten vaa ole millään sellaista, että olisi rahanarvoinen asia tuo S2-lisenssi, niin sitten vaan mitä Scawen sanoi, eli:
"You will need to write to our technical support mail."
Sitten vaan rahat takaisin ja me sanomme sitten hyvästit S2-puolella.
