Overheating while idling

[landrovered]

I don't think 20 minutes is too long, I mean, don't you think that Porsche would make sure that its cars could operate at idle without hurting themselves, it would be very poor engineering if that was not the case.

I think the problem is leaving it unattended.

I do not let my cars idle without watching the temp gauge because I have had too many Land Rovers whose clutch fans have failed. Just experience I guess. When we go offroad, I leave my truck running all day, but I keep an eye on it.

And how are you supposed to navigate city traffic without idling for long periods while stuck in traffic jams. It just makes no sense that you should not idle a modern EFI engine.
