i don't understand where is time trial? John Camaj PROMISED(!) shadow-car and time-trial mode some time ago. But I don't see it in rF2 now!
It'll be there, I made a thread about it the other day and Tim confirmed its inclusion See here: http://isiforums.net/f/showthread.php/1526-Ghost-cars-in-RF2
I saw this at one of the screenshots in the article from SimHQ: http://www.simhq.com/_motorsports6/images/motorsports_200a_015.jpg bottom right: 'transparent trainer' and 'trainer lead time'. I'm just guessing this could be the ghost car.
