How bad do the pileups in multiplayer races get?
Pileups depend on the skill of the drivers and the nature of the circuit. The Papy Cup race at Monaco, for example, was early in the season and many of the drivers were relatively inexperienced and had difficulty handling the car, never mind getting around such a challenging circuit in the middle of traffic. There were quite a few crashes. On the other hand, the Papy Cup races at Silverstone and the Nurburgring have been remarkably realistic. After several weeks of racing, the skill level of the less experienced drivers has gone up dramatically, and even at the Ring, which is an incredibly demanding track, there were relatively few crashes.
