This one basically explains itself, escape a police chase 15 times.
You can get this one pretty early in the game depending on whether or not you do a ton of violent or illegal things in game, or if you just enjoy hacking things whilst being chased. All you need to do is make the police chase you and then outrun them.
-A really simple method would be getting your wanted level activated near the docks, jumping into a boat and speeding away.
-You can also do it by racing down the streets and hacking things like steam pipes, traffic lights, bridges, etc. so that they eventually lose you.
I got this trophy without even trying to get it. So if you don't have it, don't really worry about it because odds are you will likely get it over normal gameplay.
And just for fun, here is a video I found on YouTube showing you what I wrote above.
If you like my solution please give me a like, and if you don't like it please let me know and I'll see what i can fix to make it better :)
