What telemetry is available to generate these animations? Is it all just from transponders? Are there enough transponders for such granular speed resolution? I think the FIA has direct access to some amount of onboard telemetry, which would make more sense than transponder data. If so, how is the car's lateral position determined?

I'm sure the teams are more than capable of deriving this, but how much is proprietary?

This ain't right:

"Mercedes bought Brawn for the 2010 season and built the team up to become dominant through the sports' hybrid era, winning every constructors' title to date since 2014."
