This has probably come up before but do you think it is taught or necessary to look over your shoulder to check blindspot when changing lanes on the motorway?
I just need to add an edit. I’m specifically referring to looking over your shoulder on a motorway. Checking mirrors and blindspot is not under question
Can confirm. For the curious: wing mirrors should be set wider than you might think. You shouldn’t see any part of your car in each one, you should only see what’s in the lanes next to you. Someone walking behind your car should appear in one wing mirror, then your rear view, then the other wing mirror, and not in any two of them at the same time.
Still, I glance over my shoulder when changing lanes :)
It sounds like you are describing the Car Talk method.

I used to do that too. Then I started parking by backing in, frequently (a dozen or more times per day), and found that being able to see the rear corners of my vehicle in the mirrors was infinitely more useful.
I use a pair of small (2"x2" maybe) cheap adjustable adhesive parabolic mirrors, one at the outer bottom corner of each side view mirror and angled down towards the rear wheels for this purpose.
That way they are there for backing in or lining up the back of the vehicle pulling in, but the main mirrors can be aimed better for general use.
Thanks! That is a great reminder to go hunt for the still new-in-package ones I bought for exactly that purpose a few years ago.
