Pretty cool. Love me some traffic layouts. I just think you should have limited the AI tracklimits to one lane only to avoid them from overtaking and crashing into each other. Ideally they'd be smart enough to overtake AND avoid crashes, but let's face it, that'll never happen, so i think i'd prefer them to just stay on one lane.

In those there is some flickering and seemingly random switching between cameras - can't be avoided because the F3 view follows the position of the center if gravity of the selected car and it switches direction according to what lane is closest. In 2-way inevitably there is alternating between the lanes. The least flicker is seen when F3 follows a car with AI. So try to select AI car for the track side camera views in replay and from the pits.
