Don't inch out.
When exiting a parking lot or anytime you're attempting to make a left turn onto any street. Stay far enough behind so anyone turning right can see around you. Sure it's tempting as you see traffic clear up and you think you may see an opportunity, don't fall into the trap of letting your foot off of the brake if you don't really intend on going. Because what happens is when you release your foot off of the brake, your automatic transmission in your car is going to inch you forward and you risk receiving the wrath of the driver turning right because you keep blocking his view with your car.
