There can be many cases for deviation from the predetermined ideal path. (Eg road closures, request from customer, traffic conditions, driver missed a turn.) Of course the difference here seems rather large. They should have flagged it anyway. They can even simply automatically check with the customer and the driver too, to ask what happened?
