I guess we can have both
In a very personal opinion, formula 1 cars are not really suited for online simracing, meaning the gap between drivers skills can be so huge I often end up alone in a race. I really prefer slower cars when it comes to multiplayer.
In F1 2010, as long as the players are over L32, then you can have 3-4 people racing.....all thx to the level playing field wrt set up, unlike in most PC sims which are a nightmare to set up.
