For parking my 164s anyway, I have adjusted the rhs outside mirror so that while I can still see past that side of the car covering the right side lane, the mirror is tilted just enough to barely see the curb near the right rear tire and the rf corner of the car behind me. Works well.
However, yes, some just use the method of backing up til something hits (about the same way they pull into a parking slot until something hits in the front, lol). It's a worry.
