Is it possible to race against other people?

Yeah it is possible. Why do you want this? If you want to play online with some selected players then you just need to communicate with them first and take allow from them to play with you then you will select the platform. Hope it will help you.

Is that just for consoles or PC? If you're thinking of a multiplayer hosted party, a server with a dedicated tariff from companies like this could be worth checking out. Then you should be able to race online with people you know
