For one quite a few of the network cards keep the stats in hardware and don't neccessarily have a way to reset them. In other cases there is a mix of OS accumulated stats bulk updated by overflow events on the device itself.
Its a lot of complexity, and changes all over the places for the sake of a trivial userspace change. I would suggest you instead write a quick bit of perl or python that fetches the stats and then updates every second with the changes.
