I'm going to assume good faith on your part. OP is using analogy as a rhetorical device, using things in their own life that would be recognizable and transferable to others. When he says its like "speaking English", it is because he speaks English, but it can be understood that any non-English natives would insert their own mother tongue. 88% of European households and 92% of US households own at least one car. Driving, as something that once learned you take for granted since you do it pretty much daily, is something most people can related to. Even those that cant, are probably intimately familiar with those that do. It isn't something exotic and specialized, like airline pilot or submarine crewmember.
If I say "its like finding out someone ate the last of your favorite candy", it is meant to analogize a feeling of disappointment. If you personally don't like candy, I would expect that you have the ability to understand the meaning and intent and not focus on how the analogy doesn't perfectly align with your individual personal experiences and preferences. If you want to complain about how some cultures don't really eat candy, while others focus on collective sharing over individual ownership, I suppose you can.
