Why would you need it to tell you when it’s full? If it mirrored the screen of the main pump it would at least let you see how much you’ve pumped/how much it’ll cost, without needing to turn around, which is a tiny benefit but not zero. But I can’t see any benefit in it just telling you “your tank is full now”, as though the fact that it stops pumping doesn’t do that for you more effectively.
I know some people that have never filled a tank to the top, they always just put a specific amount of money worth of fuel in. Every time I filled up when I had a motorcycle I would fill it until no more would fit because not filling it to the top just means I need to visit petrol stations more often.
