Whoever wants freeaim to be mandatory for all players because "autoaim is for noobs" should be forced to drive certain vehicles being in manual transmission with clutch from old jalopies to sports cars without telling the player which car they stole is an auto or manual. They also better not complain about a hotwiring minigame or knowing if the previous driver wore out the clutch. Also each weapon should wear out for extended use so aiming should be slight inaccurate if you consider wind direction.
If it's set in Vice City, there should be a mission where a hurricane occurs and you're trying to snipe someone but the storm is messing up your aim therefore having to calculate wind direction.
In a serious tone:
This is a sarcastic poke fun towards people that want R* to remove the auto-aim feature on weapons. Sadly there are some people out there demanding that the future GTA game should have auto-aim removed and force casual players to git gud. If they want to play that card, then they are in no position to act like a double standard princess complaining about realistic vehicle mechanics / wear and tear. Fair game.
