My dd4 has become a "sore loser". I can't say I blame her though - you can only ride that thing so many times before you get tired of never winning....

Even when we all throw the game - there is no guarantee if there are other people in the other car. She can usually break 75K on her own and I don't think she's ever won.
Given I am not a CM and don't have a partner to set me up - I can usually score around 250K - 280K on my own, but I've started to feel guilty since it doesn't usually give anyone else a chance to win (especially dd4). I swear though - she gets her competitive side from her dad
