When you are doing all this slowing down do you have a stop sign or are you just slowing down because you don't know if the car sees you? Also are you keeping track of all the traffic around you? Sometimes I have to move more into the lane or move out of the right hand lane to pass someone who cuts in front of me when they are turning into a driveway.

All these things happen when I drive too some people are just careless and you have to operate your vehicle defensively. Heck they happen to my wife and she drive a huge F250 with a full box on the back with a big lightbar across the top.
