There should be a button in the pause menu to turn off traffic. Whenever I’m racing my friends in the open world, traffic interferes. It happens every time and it throws you off your line and you wreck. It’s fine if traffic is there and you’re cruising, but when you’re racing, we should be able to turn it off.

Except for street races there shouldn’t be cars obstructing passageway when performing stunts such as speed zones and traps and danger signs! I really makes no sense whatsoever!

open world simulation, consistent to me, it’s a pity there are not more traffic but, at least there is a contrast between day and night.
For stunts, use your rewind feature.
For races, custom championship as a convoy I would say.
