Over a year of producing sim racing broadcasts at UT Austin, and we kept hitting the same wall:
The tool we needed didn't exist.
I'm the co-founder and CTO of Longhorn Sim Racing. Every race weekend, our team produces live Assetto Corsa coverage — multi-camera direction, timing overlays, battle tracking. Real production, with real viewers.
And the entire workflow was held together with duct tape.
OBS in one window. Camera controls in another. Timing overlays somewhere else. Graphics triggered manually. A two-car battle goes wheel-to-wheel through Turn 6 — and nobody catches it, because the operator is buried in the wrong tab.
That's not a workflow problem. That's a missing product.
Real motorsport has purpose-built broadcast software. Sim racing has never had anything like it.
So I built it.
PitLane Director AC is a desktop application that brings AI-powered battle detection, automatic camera direction, broadcast overlays, and full OBS control into a single interface — purpose-built for Assetto Corsa league racing.
You open PitLane, and the entire race is in front of you.
The leaderboard updates live across the full grid — every car, every gap, every pit stop. The AI Director scores every battle in real time. When two cars close to within a few tenths, it flags the fight and cuts the camera before you even notice it.
Overlays trigger automatically on race events, or manually with a click. OBS scenes, sources, and recording are all controlled from the same dashboard.
One window. One operator. TV-grade production.
From apartment to product
The first version was built in my apartment in Austin, tested against replays of our own races.
It barely worked.
A leaderboard. A fragile camera switcher. Just enough to replace the four-app juggling act we were dealing with before.
But it was already better.
From there, it grew into a full production system:
- A minimap with real track geometry and live car positioning
- An event feed with automatic race event detection
- A program monitor showing exactly what's live on stream
- Five production-grade overlays: timing tower, lower third, battle graphic, telemetry HUD, and track map
All designed to respond intelligently to what's happening in the race — not just sit there statically.
And throughout the whole process, one key constraint guided everything:
The broadcaster installs nothing on drivers' machines.
No plugins. No client software. No friction.
The entire system runs from the broadcast PC and connects like a spectator.
Introducing PitLane Systems
After a month's work behind the scenes, I am excited to announce the company behind the product, PitLane Systems — and the first wave of closed beta testing for PitLane Director AC.
For those interested, I encourage you to join the waitlist to be notified as soon as we launch publicly. Alternatively, if you run a league or produce broadcasts and want to be part of early testing, feel free to reach out directly at gray@pitlanesystems.com — we're selecting a small number of teams to work with before launch.
Stay tuned for more!
