Driving is the heart of GTA, so "AI driving upgrade" trending isn't a surprise. The talk is that GTA 6's traffic and police AI have been rebuilt from the ground up. Rockstar hasn't detailed any of it, so here's the honest split between reasonable expectation and pure hype.

What's actually shown

The two trailers show busy, varied traffic and dense crowds across Vice City and the wider state. That's footage, not a mechanics breakdown — Rockstar hasn't explained how NPC drivers, pedestrians, or police behave moment to moment. What you can reasonably infer is ambition in scale: a lot of cars and people moving at once.

What's rumoured, not confirmed

The "completely rewritten AI" framing is community expectation rather than a sourced leak. There's no Rockstar statement and no strong insider claim confirming that traffic or pursuit AI has been overhauled. It's a fair guess — a new generation usually brings smarter systems, and Rockstar's RAGE engine has advanced since GTA 5 — but a guess is what it is.

What would genuinely change driving

If Rockstar does push AI forward, the differences players would feel are concrete: traffic that reacts to your driving instead of following fixed lanes, pedestrians with self-preservation, and police pursuits that adapt rather than spawn predictably. GTA 5's wanted system became readable over time; a less scriptable version would make Vice City feel alive in a way street layouts alone can't.

Treat the specifics as wishlist until Rockstar shows gameplay — likely in a later trailer closer to launch.
