Worst things? Hmmm. Probably when you're setting up for the perfect heist and some rando crashes into your getaway car right outside the bank. Scripted chaos is fun; real player chaos is just annoying.
Haha bet this guide's saved more heists than Lester. The timing on the downtown lights is a game changer - feels like you're in one of those action movies weaving through traffic with all lights green. Just got my chrome Adder through downtown without a scratch, felt like pure magic!
