it only really occurred to me since having to worry about instrument placement in this game, but all those sci-fi ships with instrument clusters stuck way out front would be completely blind from like a full quadrant or more behind them
or really any non-symmetrical arrangement... putting radars on top of tall buildings or masts only works on earth because there's nothing to see underneath whatever they're attached to
tbf though i don't think "it must be realistic!" is automatically an interesting or even good goal for fiction, it's just a thought i never really had until now
