Yes, if your engine stops, you have a problem, but you also do flying in the mountains or over the water or even over a large forest
Yes, I very much agree and would add to the list in places like the LA Basin, San Francisco, Sydney etc. where the "land clear" rules seem to be different, GA routinely fly over very built up areas for extended periods with the best option being to find a golf course or a motorway..!
Of course I don't mean to be flippant regarding the need to have a way out should the fan-stop, all I'm saying is that we are typically very lucky here with our mixed rural-urban envirnments outside of the metropolis(es) in that mostly we have landable fields nearby except for over the hills (Wales, Pennines, Scotland etc) and the Channel / Irish Sea / North Sea etc..
