"Plus, people just don't like stinky diesel buses. I mentioned this to one BRT advocate, and they started talking about CNG or even fuel cells. Oh, please."

Then the Electric BRT in Quito, Ecuador would be more to your liking. It is similar to Bogota in many ways, including very high ridership throughout the day, but quieter and cleaner, with a surprisingly smooth ride and great acceleration. Go there ... Quito is a nice city.

Trams in Quito would still have cheaper lifecycle costs and higher ridership.

Bogata's inspiration on this is Curitiba Brazil. They came up with this concept even earlier and implemented it to a similar level of success.

Good for them.
