Been thinking about this today and my opinion - it's a bad thing.
Why? It stops people having to think about what they are doing. If people don't consciously think about putting the lights on, what else are they not bothering to check?
I must have seen a dozen cars today on the A19 driving in a blizzard with no lights on at all. A lot of them were BMWs and Mercs - on which the auto headlights don't come on at all if it's bright but foggy, bright but obscured by spray, or bright but snowing.
I don't use the auto headlights in the Alfa, despite the bairn keeping on putting them on
Also, the auto wipers did everything but what I wanted today driving in snow, blizzard or spray - and yes, they're new blades. Oh, for a plain old variable intermittent like my old Mazda!
Sometimes I pine for a basic car like my Cinq, but then again I like the climate control and the comfort!
ZF, you would like my Benz,s fully adaptive HID's then.
Dimming LED running lights, linked to ambient light, main lights that auto level (and self levelling air suspension) they turn to look round corners and have a lamp that projects sideways at 5 mph.
Main beam is automatic when its dark.....when it sees a car in front or approaching it dips again, and it actually works, you see it moving the beam to stay below the plates of the cars in front.
Occasionally dips when you don't want it to on winding roads where roadside furniture is mistaken for a car, but has never in a year hit anyone with the full beam whether oncoming or in front.
I think these high output systems need all these safeguards, hate many of these aftermarket things that'd reflect unfocused light all over the place, can spot these a mile off, also as usually one isn't working...and most fitted to VW,s!
And despite the washers, the beam can get obviously scattered with dirty lenses.
The car actually has no fog lights at the front, the shape of the beam changes instead and the low level LED goes to max brightness.
