Some items to consider:

1) Where's the Coin Slot for quarters? In the non-SKS Prius, there's a Coin Slot. -- Although I've seen SOME owners use it to store the key fob while they're driving. How lame is that?)

2) Once you make it to 100 Kmiles (150 for CARB), you will randomly get a sign saying "Deposit another $3,000 for another battery".

3) If you lose BIG TIME, balloons appear all over in the car (in front of you, beside you, etc, and even popping out from beside the windshield.).

Who says this ain't a $30,000 video game?
