LOL! why are so many people getting worked up about it, so silly.
I already said before that technology is changing.
Let me start off
The old shape Merc E-class use to have these corning lights feature on their fog lamps but now the new E-class has them built into the headlamp unit itself, which of course they replace the fog lamps with DRLs. If VW spent more time doing R&D in their headlamp technology I'm sure Seat would of use it but of course VW didn't they decided to use the fog lamps as corning lights, so Seat decided to use them.
TBH Fog lights output is near enough to be DRL light output but of course Fog lights are more wide spread and pointed at the floor, with DRL light output is more narrow and focus and pointed straight forward to get on coming traffic attention (which i think is pretty glarey than fog lights).
I'm sure the facelift model of the
Ibiza will have the corning light built into the headlamp unit and replace the fogs with DRLs (same as the Fabia VRS).
I never had any problems with my corning lights from other traffic nor the police, I normally try and see if i get stopped by the police but it has never happen to me. I guess the police where i live is more up-to-date with car technology.
