not really saying the game sucks. frankly i did get hours of enjoyment from it, these are just the few nitpicky things i have.
Annoying cop chases/ over zealous cops
its really not that hard to avoid the cops in most cases, and you can still respray cars to lose your wanted level (though there are alot of vehicles you cannot enter LSC with) it is very easy to obtain a wanted level accidentally and cop chases escalate to ramming tactics and helicopters quickly. the whole mechanic gets cumbersome and annoing quickly when you just want to move on with the game.
Lack of car/truck customization options/ flat out lack of customization for certain vehicles.
there are only a few cars in the game that have any body modifications, 90% of the vehicles in the game get the standard performance crap. big pet peeve is the lack of any sort of off road modifications for trucks ect. you want to build a good old jacked up hill climber, you are SOL unless you like the sandking. also big trucks are flat out not customizable. (personal opinion that they should be, though i understand if people think it is a non issue.) as well as most vans (how the F is the Burrito non customizable... i mean it boggles my mind.)
bad choice in drivetrain for some vehicles.
again, personal pet peeve. biggest example would be the Mesa. yes i know 2 wheel drive jeeps are out there, but 4 wheel drive jeeps our just as common. the Mesa off road was even a bigger blow being 2 wheel drive as well, as it should have been 4 wheel drive. there are 4 semi tractors in the game, all in a 10 wheel configuration. none of them are 3 axle drive.
so i get my flight skill up to 100, and all planes an helicopters still spazz around like a ADHD 5 year old high on speed constantly. WTF. i get that you want it to feel "so real" but in the context of what GTA is, im not really interested in playing a flight sim. it really distracts from the feeling that you are accomplishing something when you can barely keep the nose forward.
i know unlike previous GTA games, you have a better ability to keep certain vehicles for longer periods of time. i am thankful for that, but after playing SR, i really cant stand it. id much rather have a solid way to keep cars than hope your cherry pimped out ride does not get destroyed. . just let us perma save stuff already R*.
