The truck you’re driving is rolling down a steep hill. But suddenly the brakes fail – and you can’t avoid hitting people. If you go straight, you run into a huge group of bankers. Dozens will certainly die if you plow into them. But if you turn your wheel, either right or left, you will definitely run over seniors trying to get home from a nearby BINGO hall. Only a small group would be crushed if you just twist the wheel.
