I always thought 12 cars on the grid was kind of pathetic for something like a Solstice.
It's ironic that the cars with the greatest participation have the smallest grid sizes.
I'd like to see them raise the limits for a bit. Not 40 car fields, that's too much (you can't even see 40 cars anyway, from what I hear). But 20-25 car grids for the Solstice would be good. Same for the Skip Barber. Just to see what happens. They won't do it though.
Most of my races are all alone, save for the first few laps.
