Not a demo — real logged laps

Watch the engineers read a lap you can't.

Every screen below comes from an actual logged session, read corner by corner. No cherry-picked screenshot — the same reading happens on every lap you upload.

Two things a driver can feel — and one they never can

A vertical-G spike, a lap-time delta, a center of pressure that migrates fore and aft with speed — none of that shows up on a dash. The AI race engineers pull it straight out of the same telemetry your sim already streams, and point at the ten centimetres or two millimetres that actually matter.

MONZA · VARIANTE ASCARI 2 · LAP 41

Catch #1 — a kerb strike you didn't feel

You drove the lap clean. The engineers cross-reference vertical-G against a slip signal and compare it to your own reference lap — and find a kerb strike that cost real time, not a "maybe."

Vertical-G spike right at the apex — kerb contact, not a driving mistake
+0.18s lost this lap vs. your own clean reference — measured, not guessed
vertical-G 3.8g spike lap delta +0.18s line correction +20cm wider
MARCO — RACE ENGINEER Ascari 2, lap 41: you're clipping the inside kerb at full load — not a mistake, a line 20 cm too tight. The vertical-G confirms contact; it isn't tyre noise. Cost: +0.18s this lap against your own clean reference. Widen the entry 20 cm and keep the same commitment.
MONZA · ROGGIA → PARABOLICA · CoP MIGRATION

Catch #2 — downforce your sim will never show you

No sim exposes a downforce number. The engineers deduce the center of pressure from ride height and stiffness alone — and catch it walking backward exactly where you need front grip most.

44% front at 155 km/h — through Roggia, balanced
39% front at 275 km/h — Parabolica entry, the front end empties out

Illustrative — motion exaggerated for clarity.

CoP @155 km/h 44% F CoP @275 km/h 39% F migration −5pts rearward
JAMES — RACE ENGINEER Center of pressure walks from 44% front at 155 km/h to 39% front at 275 km/h — the front empties out right where Parabolica needs it most. That's a 5-point rearward migration your dash will never show you. Front ride height −2mm, or wing +1 click, to hold the balance through the fast stuff.

This is what «the read» means

Both captures above come from the same engine behind the four reads on the home page — Balance, Roll, Weight & CoG, Center of pressure. Load your own session and the engineers point at your ten centimetres, not someone else's.
