Steering a car full of gyroscopes in fast moving traffic? Sign me up!

That's really cool, I'd never heard of these. I imagine the flywheels are horizontal so that the bus can turn without trying to change their angular momentum, but I wonder if there's any effect on banked curves or going up hills.
