OK, inspired by Canard, here are a few pictures from a bike ride from Cordóba to Almodóvar del Río.
I got a rental mountain bike in central Cordóba. It was pretty good (light). They also had ebikes for the same price (13EUR/day) but I figured it was only 52km round-trip. Also pictured: Portus Romano, which you bike under the rail lines to see. (So many trains on so many lines! I saw at least 3 different passenger trains operating on 3 different lines on my bike ride, including the high speed one running parallel to the regular one.)
This was not the high-speed line (that's walled off), so it only runs at 140.
And yes, in Córdoba (pop 328,373) they have segregated bike lanes:
Mostly I was on secondary highways outside town though. Sometimes the roundabouts were a bit scary on the N-series highways. Going to the regional CH-series highways everything was much quieter.
PS: People were riding bicycles in February, but it does get really hot in Andalucia in the summer. Maybe people don't ride their bicycles as much when it's super hot. I dunno. Certainly in Vietnam people ride motorized two-wheeled vehicles much more than bicycles.
PPS: Light-rail related news: I wanted to take the Granada LRT but didn't, because it didn't go where I wanted to. Granada also has a BRT which didn't really seem to be able to avoid traffic. I also learned about Jaén, who built a tram and never put it into paid service (!?).
