This is a sim, cars get loose, but you can catch them as long as you don't hit the grass. The A.I. seems OK, only used them once, so far. Nothing happening on the on-line severs so don't know how that goes, yet. 101 minutes played and I don't want to race anything else, maybe RaceRoom or rFactor 2, but this one is hard to turn off so far. The site Can You Run It? say my PC couldn't run this, so far I've averaged 55 fps, so you can stick it Can You Run It?!
