this trophy will not work in private mode! only public races! you do not have to finish the race, in General, the whole match can stand on the starting line! one race takes 10-15 minutes, you will need about 4-5 hours of playing time! while your driver gets the achievement, you can swim in the pool, go skiing or just have a good night's sleep!! an unpleasant surprise can be a crash of the server,but that occasionally is the place to be!
