I've just seen an electric push bike on my walk into town at lunchtime. As it went into the underpass beneath the roundabout not far from Futures Place, its lights came on automatically (both front AND rear) and then back off again once the rider had exited the underpass and back into what passes for daylight at this time of the year. 

Now if only cars could do that too.... 

My Peugeot 508 does that when set to auto lights.  DRL then full lights when the sensors think it is needed.  There is one slight flaw in the system.  When it snows it thinks that full lights front and back are not needed so I then switch to manual overide.  Also in foggy conditions I sometimes need to manual overide it.

Is that both front and rear lights though Sergio? Many cars I see on my daily commute will have only the front DRLs on with nothing on the back. It's a bit scary when you come up behind someone in thick fog with no lights on the back but their fancy LED strip lights on the front are on so they think that's sufficient! 

I've recently had a dash cam fitted to one of my vehicles as I'm fed up of drivers cutting tight in front of it to turn off at a junction rather than pulling in behind to wait a few seconds. My truck is 2 tonne and doesn't stop on a penny like my usual mode of transport can! I have a lot of renewed sympathy for truck drivers... In a recent commute to work in heavy rain I'd say there were around 2 in 10 cars on the road that were not sporting rear lights on their cars. Overtaking them and you could see their DRLs were on but no lights at the back where it's really needed especially on motorways and small country lanes! 

Is that both front and rear lights though

On my other half's car it is - front DRLs when it thinks it's daylight, sidelights/dipped headlights front and rear when it thinks it's dark.

On my car front DRLs when it thinks it's daylight.  No rear lights at all

sidelights/dipped headlights front and rear when it thinks it's dark or you enter a tunnel

When there is fog front and rear lights have to be turn on by the driver. 

I have always thought it was a poor design decision not to make the vehicle visiable from the rear with lights if they deem it is needed to have the front of the vehicle visiable by DLRs

Yes I fully agree Sergio Fernandez 

Again this morning, driving into work in rain and drizzle and many cars do not have rear lights on but their DRLs are on at the front.  I'm astounded that Automotive designers haven't addressed this by now! 

I saw this a few days ago and meant to post a link - looks like something might be happening about the light glare:

It is not just the glare that is the issue.  A lot of car coming out of the factory or the main dealer showroom have the lights set at the wrong height and the wrong beam angle.  The motor trade are well aware of it, they choose to ignore it. 

That should be picked up at an MOT though surely Sergio? I know they test it on mine as they've picked up on it after I'd had a new headlight installed. 

The problem I have is that my car is rather 'low' to the ground and everyone else seems to have SUV's that sit a lot higher than me. Meaning that their headlights are right in my eyeline anyway... 

It seems to be the social norm nowadays to look after oneself with no regard to how your actions affect those around you i.e. "I'll have the brightest lights on my car so I can see and I don't care if it dazzles everyone else on the road." 

I read a comment on a YouTube video the other day (my guilty pleasure is watching dashcam videos of bad driving, most of the time by those with the dashcam themselves!!! ) where someone said 'Drive like it's a collaboration, not a competition' which I thought was a really nice mantra 

Loading of the vehicle also has an effect. Mine have had adjusters to lower the lights when there is a heavy load at the rear. How many people use this function?
