OneSync: how do you handle vehicle sync conflicts during heavy traffic?

Specific scenario: 60 players on a busy intersection, NPCs disabled. Two players trying to drive through each other end up in a desync — both see the other player's car at a slightly different position, leading to "ghost crashes".

I've tried:

• Forcing higher netGameEventHandler priority for vehicles → minor improvement
• Custom interpolation on the client side → made it worse, vehicles "jitter" between predicted and authoritative positions
• Reducing network event frequency → makes the desync visible for longer

Has anyone solved this elegantly?

The root cause feels like FiveM's prediction model isn't well-tuned for high-density vehicle interactions, but I refuse to accept "buy more bandwidth" as the answer.

Open to ANY ideas, even hacky ones.
