Ever since the minigame has been fixed and more reliable (going from a server-side script to a client-side script) I think the pick locking and hotwire minigame should be less tries but more difficult.
The only way for you to really fail is if you aren't paying attention because currently, all of the cars you hotwire and pick are super slow and easy, you just have to do it 50 times in a row give or take. I think that the bar should move faster and maybe have the green zone be a bit smaller, but you have to do it in half the amount of attempts (25 maybe?). This way you actually have sometimes to fail rather than your only chance of being caught is spending 5 minutes in a stationary car just waiting for a cop to drive by.
I haven't used a lockpicking kit in a while, so I don't know if that lowers the amount of attempts, I have been kind of lazy, but regardless I still think this would be a positive addition to the game.
(I think the same about dismantling the entire chop setup with how slow it is, you can't really fail because of how easy it is, maybe speed that up and have it take fewer attempts as well)
