I don't doubt that at all - I'm just puzzled how you could adapt controllers (and yourself) to the relatively reaction demanding task of flying a space ship in Elite and then be super-slow in browsing the menus.
But you are absolutely right that five minutes is simply too long of a wait anyway and there's no loitering time that would be short enough unless it fell to 1-2 minutes. I'd just relog rather than wait for AFKer to be evacuated if it was five. Limits would only be reasonable on CG megaships/outposts, and even in that case just slapping some more pads would be far preferable.
It's not just physical disabilities either, the game has to cater for players with learning difficulties too. There are players here on various levels of the autism spectrum, players with dyslexia, various other mental difficulties - all of which can increase the time needed in dock. That alone implies that imposing a landing time limit simply isn't appropriate.
There was a survey back in 2014 showing that 5-6% of players required either adapted tech or a modified control setup due to how their particular issue affected them.
Now this may seem off-topic, it isn't. I am looking at the need for more focus on a reasonable size of players that are disabled. Thare seem to be a higher number than I thought.

Of course, being on the forums here means that survey only really covers a small percentage of players and ex players. But is shows that there are players whom may be affected adversely by implementing such a limit.
Being AFK is a different story, AFK players should be automatically logged off after a period of time, or, at least, moved into their own instance. Active players, no, AFK players yes, something akin to new players (I believe they are in their own instance until either take off or that first jump).
