I feel that being a criminal player its much harder to escape police now when they have all this equipment like drags, super cars, helicopters and regular cruisers that go 200+. Making it almost impossible to get away from. The best chance you have getting away is the sewers as its tight and helicopters can't see you, however there is only one entrance then you are blocked in. You then are most likely to get caught and have 6 hours jail time. If all tunnels and entrances are unblocked then it would make it a more fair for crim players. It would also open up more RP situations and experiences.
Positives: Easier to escape making it fair, more RP situations, more places to explore.
Negatives: Players abusing it too much. (solution would be for PD to counter it)
