Oh cool, so the cars will tend to try overtake
I think if you have a normal single carriageway road, and have splines on each side of the road as usual, but let the splines run both lanes on straights or wider bits of road, it could kinda 'fake' nice overtaking from the AI only where it is appropriate. BUT, that would then mean AI runs where you want to run the racing line and full road wouldn't work.
Iirc, do AI splines record allowing overtaking or not, I guess that could be a way to lock out overtaking where it's not sensible!?
That said, having AI randomly overtake in bad places, or cut corners where it's not appropriate might be a nice twist to the driving, having you need to take care, look ahead well, take sensible speeds so you have space to stop/swerve through certain bends etc etc...
Those elements are what make fast but safe road driving so enjoyable for me, keeping you on your toes and being safe through good observation and forward thinking etc
The best bit is, you can experiment these techniques in Racer in Murcielago's and Veyrons etc and push your luck and just see what happens etc, while in real life it's not such a good idea to 'experiment' hehe.
Hmmmm, I didn't want to spend time playing with this idea but I think I might have to give it a whirl later tonight. It's so much more possible now with the use mesh hits capability.
That said, authoring the splines in TrackEd (keyframe cameras, or just putting the splines down) will be a total nightmare with splines overlaying each other
Also, I wonder if splines criss-crossing will work ok... maybe starting grids will need to not be on overlaying splines so the AI can find the 'order' of the splines and so direction it should look for the next/last spline... hmmmm...
Hmmmm....
