> Requiring multiple sensors means that all of your sensor systems need to notice a danger
This is the opposite of true. In well-designed sensor fusion algorithms, every new piece of sensor data, however noisy, helps to overconstrain the estimate. Each sensor reading helps to inform the interpretation of the other readings. If your system is designed such that more information worsens your inference, you have designed a terrible system.
