A race engineer worth trusting.
A race engineer is not more useful because it talks more. It is more useful when the few things it says deserve to be believed.
Fuel is a good example. A consumption estimate needs usable evidence; an unavailable estimate is not zero fuel. “Pit this lap” keeps its conservative fuel-lap margin. It is advice from the facts LapMind has, not a promise about what the car can do.
The optional lap summary brings available elapsed time, lap time, position and fuel laps remaining into one report. Eligible New Best and comparison information can be included. Missing facts stay missing, and routine summaries do not override the pit or finish exclusions.
Timed elapsed announcements have their own controls. Timed-race Final Lap remains deliberately unavailable: a plausible guess is not a trustworthy last-lap signal. Silence is the better outcome when GT7 does not provide enough evidence.
What happens after the race matters too. Normal Sessions retain available detailed lap telemetry locally, in a compact compressed format. A saved lap can return to LAB without asking the user to make a support capture first.
Diagnostics is a separate, explicit 5 Hz recorder: Start, Stop and Export. It is not the normal Session pipeline and it does not silently upload anything.
These are implemented behaviours, not a report of a new physical drive. The current-candidate 30–60-minute GT7 runtime and performance check is still open. Source checks can explain an intended boundary; only the real run can show how the whole experience holds together.
The rule is still the same: keep the facts, leave out the invented confidence.
