For maximum boredom find a sim with the Avus track, 2 very long straights connected with 2 very short turns. Having driven Avus in GPL I appreciate your sentiments. Can't agree with historical Spa being boring though. I virtually pee myself there every time. IRL the Grand Prix Drivers Association eventually said no more. SW
Holy cow. No way would I race that track unless there were 500 cars of 5 different categories as moving chicanes and a $1M prize LOL. I edited the OP significantly to remove the Spa reference as there are exceptions to every rule but there are many out there who are seeking these types of tracks I believe.
