i was playing NASCAR series for the first time last night. my Bob is doing well for the superspeed way, until lap 16, with 9second lead, the joker pit in without my command. l noticed that the tyres were in bad shapde then, but i never thought that Bob is capable of pit in on his own.i switched to sports soft for the seconf try, the same thing happened again,
