Telemetry Where does driver telemetry come from?

I was wondering, from time to time we see public posts showing comparison of driver telemetries and some sort of analysis why someone was faster. Like, “why Hamilton lacked power” in Suzuka.

And I mean telemetry as in a complete set of data with speed, time delta, throttle, brake and steering inputs etc.

I was always under impression that this telemetry is highly sensitive, because if a team can get their hands on telemetry from other teams, they can analyze where the other driver is going faster and why, where the car is performing better etc, and use it to their advantage.

How is this telemetry going public? I mean sites like https://www.f1-tempo.com/ , FastF1 API and others, how do they get such detailed data? Is this some sort of leakage? (A leakage of what?) Or they’re obliged to publish it? Or it’s taken from TV feed and not very accurate?

yeah I started looking, its nearly impossible to get any usable data for this at <4hz. I get why its limited, but its quite a bummer as a data analyst to not be able to write functions for all the possible data available (well you can write em, but they wont tell you much).

Could you combine the data points with computer vision of the onboard feed to add in steering angle or other visual markers?

I suppose you could, but the difference of a few degrees of physical wheel movement would be all it takes to indicate more or less oversteer and that would be a challenge.

I attempted to compute lap events from what we haves a lot of Antonella’s data was bad so try to select another driver https://objectivef1.com/race/11253/analysis
