Well since we're talking about charges sticking to vehicles I think we've come up with a concept for a while new powerup. Keep the mines somewhat how they are, but add another "Magnetized Charges" powerup that does the things you're talking about (Transfer on physical contact, drops if the car flips, etc).
OK, tell it to me straight... in Rollcage Stage II for the PS1... was Winter Wonderland II even possible to Gold Medal...?
