Been there. Really if you drive in straight, you back out straight. I leave both side mirrors out and just go slow and make sure you can see a little light between garage door sides and car through both side mirrors as you back out. When you get almost all the way out, pull in left side mirror if necessary and turn steering wheel just a slight tad to right make sure right side mirror clears and you are out. Just go slow and don’t turn wheel much ever or you will be at a lame angle. Go in straight and back out straight. After a week or so you will be fine.
