Why in the world is it called
Kaohsiung Walking? Whoever chose this name never tried walking in Kaohsiung. Kaohsiung is a terrible city for walking.
Crossing the street on foot is dangerous because the cars and especially the motorcycles try to cut it as close as they can, not to speak of the motorcycles driving across the crosswalk, often against traffic regulations. Cars and motorcycles both stop on the crosswalks, making it hard to cross. Even if they obeyed the regulations, most Taiwan cities have the ridiculous rule where it's legal to turn right on red lights WITHOUT STOPPING!
Then assuming you can reach the sidewalk without getting injured, you have to dodge the motorcycles driving on the sidewalk at the same speed they do on the street. The arcade walkways 騎樓 are blocked by parked motorcycles, other vehicles, and miscellaneous junk.
