Cop cars are balanced. Sorry you have trouble evading but you can get away pretty easily if you know what you're doing.
Not sure where you are getting the "they get free maxed cars that are faster than any other car out there". That's legit just not true lmao.
It's so hypocritical to say the cars LEOs have right now and their ways of catching criminals is bad and unhealthy RP.
Is it good RP to be whipping around drag bikes that you would never see outside the race track and cars that realistically only the top 1% could afford? Is it good RP to have an ambush set up everytime someone is getting chased? LEO factions adjust their strategies and get new vehicles based off what criminal RPers are starting to use.
There is also massive wealth gaps between criminal RPers. You have people with many millions then you have the new players with 5k in their bank. It sucks for the new players that their stolen Glendale is not going to perform as well as a police cruiser but it is not possible to accommodate for them when most the server uses cars that go 200+
It's also pretty obvious why 1/1 cars mostly go well under the speed cap and that's to prevent poor RP. 1/1 cars are meant to be eye candy, not meta cars. There are plenty of cars that are 300-400k that go much faster than any normal police car.
