I guess I wasn't real clear. I did not mean to imply there was such a low oil shut down on the vehicle. I only meant to say that the ony way to be sure the engine was (or was not) seized is to use the method I described. For the record there are some small engines for lawn tractors and the like that do have a low oil shut off that is a simple ground circuit that is interupted if the oil reservoir drops to an unsafe level. This is where some people get the idea all engines have it. Sorry if I was misunderstood.
As far as implimentation, it would not be hard (as Wrenchtech indicated) for them to wire in a warning that gave a short amount of time to bring the vehicle to a safe stop when a severley low oil condition indicated. Most engines would be able to withstand even a brief low oil pressure condition over a no oil pressure condition. Repair/replacement revenues are the most likely reason the effort has not been made to develope this further.
