I have somewhat of the same problem ,so what i have done is make sure
the shade behind the pass seat is up before i start out from home and then i try to square as best as i can when i get to the Y intersection this helps me a lot but ! if we had a mirror on the front that we could swing out and see to our right it would make it better .I saw a school bus with a arm in front that swung out to make the kids get farther out in front of the bus so the driver could see them and that would work with a mirror on it BUT!guess what that cost?all intersections should be T not y.
