I'm not an expert in the genre, but I am a big fan of Neuromancer. I skimmed the article, and while I agree that the "cyberpunk" aesthetic has practically evolved into self parody, I'm not sure I agree about the analysis/critique of the genre.
IMO the core of cyberpunk is about envisioning a world where advanced technology is useful and ubiquitous, yet humanity is worse off than ever ("high tech, low life"). It's a subversion of the simple tech dystopias where the technology itself is evil or is misused by evil people, and more of a realistic counterpoint to the idea that technological progress leads to inevitable utopia.
I'm not sure about more contemporary works that build on those themes. Maybe it's lost its edge as "futuristic" technology has pushed its way more and more into our lives?
Taxis are complementary to the higher-priority parts of the hierarchy. It's easier to commit to walking/cycling/public transport knowing that you can always take a taxi in a pinch. SOVs have the inverse effect - it's hard to combine them with other modes of transportation, and if you're already paying to own/maintain/insure a vehicle, you're incentivized away from considering alternatives.
The hierarchy isn't so much about how green each individual option is, but rather about how trips should be distributed to reach an overall optimum.
For short trips or connections, walking should be more convenient because you don't need any gear or space to store your bike. This also gives a multiplicative effect with other transport options, because (e.g.) people are much more likely to take a bus or train if they can walk directly to the station instead of needing a bike or car to get there in the first place.
As an aside, mature bicycle infrastructure goes beyond bike lanes, especially as the number of cyclists grows. For instance, here's a video showing off a huge bicycle parking facility in Amsterdam: https://youtu.be/EqwasBTzZS8?t=530. Obviously this is great compared to car parking, but it's still a lot compared to the infrastructure needed to support short walking trips.
