I highly recommend it. The only problem is that you rely on your RVM almost exclusively until a car is almost beside you, which becomes a problem if you have rear seat passengers and their heads block your view.
I have actually had my SVMs adjusted as displayed in the article, for a few years now. The only problems I ever have is if my rear windshield fogs up. Even then, if you lean towards the SVM in question, you can still get a straight back view. Not having to look over my shoulder has done wonders for me. As to big fros...issue hats to be worn at all times. :> I highly reccommend adjust your SVMs in this way.
I don't recall where I picked up the habit, but I too have used this set up for most of my driving years. About have the wife converted. This really helps in my SUV with really dark tint.
If I lived ON the interstate; only ever had to worry about lane-changes; NEVER had to parallel park, to negotiate a crowded city parking-lot, or a downed tree(I do live in the country) . . . .
I'd be all over this.
Unfortunately, I live in a world with X-band,
tight, low-speed maneuvering(city and country) AND parking garages.
Knowingly the precise relationship between my vehicle and it's immediate environment is vital
On the interstate; I constantly monitor my mirrors, never allowing any vehicle to 'camp' in a blind-spot.
Of course, going faster than the 'pace' helps
