Making left turns in the car...well, round 5

I guess all those years of pulling horse trailers I have learned how to turn left without taking off the front end of someones car. It always amazes me when I am at a stop sign waiting to go and someone turning left onto the road Im on...gives me all the dirty looks because they need my lane to make a left turn. I really bewildered one poor lady one day because she was a little ways into the road so that she could see and I managed to turn onto her road without even coming close to hitting her. You could tell she wanted to back up to give me room but there was a car behind her. I wish I had a picture of the look on her face...come on lady I drive a Subaru Forrester...how much room do I need! LOL
