That's a kind of brute force approach. It seems sub optimal but I don't know how to reason about it.
Should I say that observing every vehicle across the median on the oncoming carriageway is inefficient? Well I can't say that because occasionally some small cargo or even a wheel falls off and bounds across to the oncoming lane - something you definitely want to see coming.
Perhaps taking a zonal approach is as effective and certainly less taxing on the driver.
Scan each zone, some zones get scanned more frequently, and look for anything unusual.
