Thank you for your reply! It was very interesting to read.
I enjoy cycling, and I like it especially for commuting. However, my city isn't really bicycle friendly. I only know of one very short bicycle road near a library, but unfortunately many pedestrians don't abide it; despite clear signs saying it's a road for bicycle. And it's also the other way around there - cyclists driving on the sidewalk, where pedestrians are also walking. It makes this road somewhat obsolete.
There's also a promenade with a wide road for bicycles and pedestrians, and it's actually not bad, but it's mostly for sports rather than commuting.
Cyclists in my city must drive on the road next to cars then, when trying to get from place to place; which is significantly more dangerous. And it seems to cause many unfortunate accidents. It's quite dangerous by itself, but sadly some drivers can be quite reckless. My father got badly injured when cycling because a taxi driver opened a door to let a passenger out in the middle of the road, and my father crashed into the door. My friend in elementary school lost his grandfather in a bicycle accident as well.
Because of that, I don't cycle anymore, but I used to go to school by bicycle in middle school. I faced some different problems back then. I once prepared to take my bike after a school day, and found my seat perforated. It was so frustrating, because it felt like it had absolutely no purpose. Other than that, I had some bicycle parts stolen a few times.
Another problem I faced, which isn't as bad as the others, but just affected me personally: it was hard to find affordable bicycles for my size. I'm 187 centimeters tall (when I used to cycle I was shorter, but still significantly taller than average), so I needed a big bicycle. There were some available, but they were very expensive. We ended up getting a used bicycle for cheaper.
Sorry for making it so long, but you said "I cannot actually compare the case with that of the other countries because I do not know what it is in the countries.", so I ended up writing how it is where I live (Nahariya). Also, I just counted, and I wrote bicycle nine times haha. And now it went up to ten.
And thanks for the feedback on my Japanese! I'm still learning, so I really appreciate it.
