I don't see why not if you're back in time.
All I'd ask is that if you don't have a setup or know your way around the circuit then consider starting from the pit to avoid any nasty lap 1 incidents.
On the subject of incidents we have a very good sized grid tonight so the risk is high. Please try and race safely especially in race 2.
If you're a slower driver being caught and are happy to be passed don't go dancing all over the road trying to make space in any location you feel unsafe doing so, or just as a car catches you.
A faster car will find its own way if they decide to pass on a corner or braking zone, if you stay on the line and stay predictable then accidents are fair less likely!
For this to remain fun we need to stay aware of the rules and each other, I'd rather not have to put my moderators hat on but would also rather that any dodgy driving is reported so we can improve future races.
For anyone who doesn't have it I'd recommend helicorsa, which you can find on Racedepartment. That should help make sure you know where surrounding cars are.
