Just wondering about this...
Haven't completed the game yet, but I see the guides say you have to be in the mini games to get the extra upgrades, but on the annoying bagpipe one, I quit the mini game as I was on the gold part, and it slowed th car back to to normal speed and I was allowed to shoot the safe and sink, and it awarded me the prize.
My question to this is:
Does it effect the achievement
and the one thing I am not sure about is do I have to complete the gold trial? Or is it one prize for just the first drive and the safe shooting bits etc?
