My previous car had auto lights, but you had to manually switch to main beam (the blue light) on dark stretches with no street lights, which you then manually turned off when you saw a car approached so as not to dazzle them.
My new car (2 years old, same make, different model) also has auto lights, including auto main beam, but the trouble I found with this was that it didn't automatically turn off the main beam, when cars were approaching, quick enough, which resulted, understandably, in lots of approaching cars flashing me because I was dazzling them.
I had to resort to the manual to learn how to manually turn the auto main beam off...and as a man, I almost never read manuals of any kind!
