Still confused on one thing
I know for sure on PAX they said you could go "off-road" since they took the dirt path, but idk if they meant on freely steering on wide field as well or not.
They said "if it's a road, you can drive on it"
The car is only for the road. I believe the only thing they did was remove the invisible barrier, so you might be able to go off exploring, but it will probably still try to steer you back into the road like the old builds. And you still won't be able to park anywhere.
And, of course, there's still absolutely no reason to take your car off-roading. That's what chocobos are for, and they are far superior.
