Haven’t seen the EngineBraking podcast mentioned. It’s 2 ex-F1 staff (performance/sim engineer and something in IT systems) and they always have good analysis.
They have a RB bias, but they’re aware of it and regularly call it out, as well as trying to pick a new team each week to follow.
I also don’t hate the Pitstop podcast, which is 2 guys who got into F1 just over a season ago. It’s interesting to hear things from a completely new fans perspective. They also have really good guest interviews with the lesser known people of F1. They are new to the sport and definitely have some opinions that will make any long time watcher cringe, but they’re fun to listen to.
