You know that when you get drunk the best option is to call Roman to send a car for you. I don't know what I'm doing wrong but I can't enter the car in 100% of the times... I just don't get it, i just go next to the passenger door and press F but no matter how many times I do it, Niko is just sitting there doing nothing. Is that some glitch or I don't do it right?
I have the steam version of GTA IV and it is the latest version if this will help you.
