And that is why I ALWAYS check again (and again) before making a lane change, and while making the lane change, I even look out the side window just to be certain I didn't miss something. Entering interstates are the worst, especially in large cities. As someone else said, you'll get used to it after a while.
Another thing that has sometimes been problematic for me is when a lane change is necessary in bumper to bumper traffic and some kind soul drops back to let you in allowing only a few feet of clearance and you wonder, is it just someone being cautious, or can I turn? If you don't fill the gap in a very short time someone else will. Your camera should help with that.
