In a C150, nearly ran into a stone wall at the end of a short runway once. If you decide as soon as you touch down, or before, that there's not room to stop, then it's not a problem. In my case there should have been room to stop, but it wasn't till I applied the brakes that I realised how slippery it was. So when I realised I was even further down the runway and also, by braking, I had lost the necessary airspeed to lift off again. If I'd continued I'd have been into the wall, or through it and over the cliff beyond.
Fortunately I managed to swing it round and ended up facing the opposite way on the grass about 30 m off to one side of the runway. If it'd been a car it would have rolled over, since it was still going quite fast. Also fortunately it's not a tail dragger. Still can't believe it stayed upright, but definitely worth knowing for if it happens again. Spectator applauded and thought this dramatic arrival was planned!
It goes to show, though, that go-around and touch-and-go decisions are sometimes affected by factors other than the obvious.
