The car horn is a safety feature that is designed to be used as a warning mechanism. It's a poor analogy to compare it to "comfort", which literally translates into the passenger in the back also reclining and reclaiming the same amount of space. At the end of the day, the person paid for a seat and that seat comes with comfort features that they can use. To reiterate, it's a poor analogy as no one is honking at you or keeping you from sleeping or waking you up or whatever else a random car horn would do to you at 3 am (at which point you should be calling the authorities because if you live in a civilized place, that ought to be illegal)
