質問: could you please give me an example sentence in which is natural to use 乗車する instead of 乗る? could you please give me an example sentence in which is natural to use 乗車する instead of 乗る?
回答: 乗車する is more likely to be used in formal situations than 乗る because it is limited to the meaning of "to get on to the vehicle". ・タクシーに乗る/タクシーに乗車する ・バスに乗る/バスに乗車する ・電車に乗る (車 is repetitive, so 「電車に乗車する」 is unnatural) ・始発駅から乗車する (since i have already mentioned the word "駅(station)", there is no need to mention the word "電車(train)", but 乗る alone would be insufficient information.) ・飛行機に乗る/飛行機に搭乗する (乗車 is not available for airplanes. use 搭乗 instead.)
