I have a problem with how the helicopters work. If you have 2-3 stars, you pretty much have to hide under something to get away. All the time I'll be waiting in an alleyway for my stars to drop, and blam, along comes a helicopter out of nowhere and spots me.
Other than that, I don't mind the difficulty. A lot of the good tips have already been said here: drive down alleys, switch cars, swerve back and forth to avoid getting rammed, etc.
Consider trying this.. Lose the police ground units then stop in a rather open environment and fire on the choppers with your assault riffle. For choppers to effectively become a variable in pursuits they have to fly low enough so their side gunner has good range as even shooting directly downward a few hundred meters your bullet is going to be slowed by atmospheric friction. GTA 5's helicopters react more realistically to ground fire and i have been able to bring down a few with assault riffle rounds, you will know when a chopper loses control, you will hear it and see it, and they sometimes announce it on the police radio. I'm not exactly what point to fire on in the chopper, we need to experiment with hitting the main rotor or the tail rotor or the pilot himself. In reality the tail rotor is going to be more vulnerable and present a better target profile to ground fire.
You can even shoot the lights out on the chopper but i have only done that once in a mission where the chopper flys very close though this could be viable.
While this isn't exactly the most realistic depiction of a pursuit, most choppers would be flying at ranges that assault riffles would be rendered ineffective, it enriches gameplay giving you more recourse against air reconnaissance than existed in 4 if you have the skill or opportunity to take advantage of the chopper vulnerability.
If you can take down two choppers you can purge the sky of some time from air units effectively taking out the eyes of the police dispatcher. Ground units may find you while your doing this but i have found that this creates a significant window to remove air recon from the pursuit.
Hiding under stuff works but you do have other options which just makes gameplay all the better.
You are not going to be able to outrun the police in most situations directly. You have to use the environment strategically. game AI has terrible ability to navigate non-street environments. You need to consider using alley ways. Once you enter an alleyway cops are likely to lose it in these narrow environments, You break pursuit here and now you can outrun them..
This is the ticket. If you watch police chases, they never lose the police on the freeway. The few times they do, it's in the cut, and usually in the woods. There is just too much visibility on the freeway, and the high rate of speed causes more danger for you than the police following.
You need to break line of sight: it's much more realistic than any previous game.
I know i have been down on the driving in other threads but as far as pursuits go they are infinitely better in GTA 5 than gta 4 when you get near 4 stars.
One last tip... Containers. Everybody here recognizse that stealth plays a role here and it's possible to actually drive your car, if it's small enough, into a freight container with open doors(the things trucks haul goods in).
I have evaded 4 stars by hiding in one of these despite choppers shinning their lights directly on the roof of the container.
