Earlier in the thread I posted about AI cars at Sardegna running out of fuel
and staying on the track. I had a nasty crash as I rounded the sweeper onto the finishing straight and encounter a train of 4 or 5 cars at 50MPH! After pounding the trailing car, I hit the outside barrier and then spun across the track to the barrier before pit in. Car was hurt for half a lap or so, but I still got the CRB! I don't think it's possible to lose the CRB on this race!
A car that does this and never pits will finish 5 laps down to my R92, while the rest of the field is one lap down, with tail-enders two laps. Other AI cars will sometimes get "stuck" behind the out-of-fuel car as it trundles around at 50 mph, but they usually figure it out pretty quickly. and move around him. Once in a while, though, you get
several cars lined up behind him, and the AI is definitely lacking some "I" in that case!
This one race, in which I was running the Tomahawk S as I found suggested elsewhere, had three such trains I found while following C. Lopez around in the replay. The first was his 7th lap, my 9th, and the others stuck behind him were on their 8th lap, about to put Lopez a lap down to them. (Lopez passed the pit entrance finishing his 6th lap and was out of fuel by the end of the straight, I think.) The 19th-place car hadn't caught the train yet when it finally dispersed, but this was 13th to 18th lined up behind him.
There were two smaller trains later in the race: In the last one the Alfa had
just figured out he could move around and pass.
