If fusing two data sources is necessary prior to making actuation decisions, how could adding another data source not introduce additional processing & latency?
It's not just about paying more dollars, but also range.
You're assuming that a dual system will be safer, but what if such systems are more prone to perception confusion, or other anomalies?
Even if a dual system were safer, it doesn't make sense to say that you will pay for safety absolutely. For example, you can always add an additional smoke alarm to your house for some marginal improvement in safety, but at some point most people decide they are safe enough.
