I was driving on a reasonably remote highway in Victoria Australia. My car was running low on petrol. As I approached an exit there was a sign that said last service for 90km or something like this. I did some mental maths and decided I could make it another 90km so pushed on. The fuel warning light came on about half way through the 90km. When I reached the exit the pump was out of order and station closed (tiny rural station). Now I was forced either to turn back or push on to next station. I decided to push on and ended up running out of petrol I had to call roadside assistance. If I hadn't seen the sign saying the next service was 90 km away I would have pulled in then and there.
