I think people are conflating Elon's answers to questions on the $25K car such that they think Tesla isn't working on it because they think they'll solve FSD this year.
In reality, I think Elon responded directly to the question by affirming that demand for existing products is so strong, and will allow such a high volume ramp, that there's no need to release or even talk about a $25K car at this time, which would only lower output and take sales away from higher margin vehicles (makes perfect sense). And as part of that process, his mind instantly goes to: "When we solve FSD, a $25K car becomes moot."
It takes careful parsing to separate the two, and I think one could be forgiven when interpreting his answer as: "No $25K car because FSD!"
