There’s an Easter Egg menu.
I don’t know why farts are so funny but you just can’t help giggling when farting sounds come every time you use the indicator. Having said that, I was very keen to deactivate this mode after about ten minutes. You can only take so much fun while you’re driving.
Haven’t tried romance mode yet. As it’s winter and we have the whole house to ourselves it’s much more pleasant to ignore each other in front of a real (gas) fire in our lounge.
