With the grid spots being almost impossible to setup on an oval in AC, I propose that when we go to the grid, we land pretty hard and face up the track at 45 degrees, this is to stop the AI spinning out at the start, that as soon as we can grab a gear we should take off, with care remembering how hard it is to start on an oval, drive around through the pits, getting rid of the penalty, and then form up for a rolling start. Slightly quicker this way and I'm a little worried the rough spawn at the start may actually damage a car.
Remember, each driver gets one caution each per race, call out nice and loud and repeatedly on Discord (or map a quick chat button). Nominally the last person will call the green flag whenever they are ready, at any point on the track.
Call (or quickchat) 'Green, Green, Green', loudly and the caller can not overtake in the nearest corner to their call. (let's say ovals only have two corners OK)
Call '1, 2, 3, Green, Green, Green' if you like, six half dozens.
