We dont have to increase the overall grid at all. If we just moved each bike slightly back from the next. It could be a bike length, half a bike length, etc. I dont know how much room there currently is from bike spot #1 and #4. No one gets farther away except the very last two riders, and it would only be by a matter of feet. I would love to see this setup for all classes, as having different dots for different classes would be a pain. I also think that the rider gridded at a higher grid position should have an advantage over the next riders.

Here is what I'm talking about.
