They did similar things in Seoul (albeit not nearly as beautiful), and I've seen them in Japan. You're not going to have many bugs, because at the end of the day it's still only a dozen meters wide in the middle of the city.
This is because they're too south to be northerners and to north to be southerners. The literal middle child of England. Every time you have to drive down south and it's either pay to take the M6 toll road or deal with going closer to Birmingham, every stingy northerner is thinking in their head "fuck, this is a difficult choice".
