While car analogies are notoriously bad, it's much more like "I'm going to buy a plug-in hybrid and use gasoline until charging stations are widely available". You can write code that works in Python 2 that takes zero effort to run in Python 3. I (and many others) have been doing this for years. Just look at the number of packages on PyPI that run, unmodified, on 2 and 3. [Edit: gas -> gasoline]

  I try to write compatible code myself too, and the only reason it's "zero effort" to run in Python 3 is that I've already invested said effort when making it compatible. Getting strings and paths and stdio to be cross-compatible and working correctly in both 2 and 3 can be quite painful in my experience. Which was kind of my point with the vehicle analogy. It requires a significant investment that you're ignoring, and lack of enough underlying support to justify it during that time.

Driving an EV without charging stations is (nearly) useless. You can still run Python 2-3 code with a Python 2 interpreter with no significant consequence.

  EV drivers don't need charging stations at all if they have an open plug at home or at work. The metaphor still sort of works that Python developers had plenty of time where maybe they didn't have enough charging stations on the wide open highway roads of Production to use Python 3 there, but certainly could have been happy to use an EV to commute from home (hobby projects) to the work parking lot (side projects, automation projects, new projects) and back while they waited for those "charging stations" to be built.

    I don't want to debate the amount of shoehorning necessary to validate the metaphor. We all understand concretely the issue at hand, the metaphor is only obfuscating at this point.
