It seems console players are the worst about cheating. Top speed, driving right through traffic as if were not even there. They like to use their speed hacks to run to the finish line as racers and crashbust you as cops. No skill to park next to a wrecked vehicle.
It's really hard for console players to cheat, so that's a no.
And the reason why players are able to go through traffic is because traffics aren't synced properly across all systems, so for their POV, there isn't any traffic but for your POV, there is traffic in front of them and they can pass like nothing's in front of them.
If its a sync problem, why do the console players who this happens to never react to ANY traffic? Does the console version not have traffic? It doesn't happen to all players, just some because I've watched them, Some of the cars even vibrate a little when going through traffic. So I really don't think it is a sync problem
