I also had trouble adjusting to the blind spots ... mostly the rear passenger side pillar. The trick I learned is to make sure that the passenger seat isn't all the way back. If it IS all the way back, the headrest combines with the pillar to make a huge blind spot. Move the passenger seat forward until you can see through at least some of the window behind the headrest and you'll be able to tell if a vehicle is there. But be sure to use your mirrors too.
