“Pay to enable” only works where you already have the hardware fitted… the SR+ doesn’t have the fog lights.Driving in the fog last night in my SR+, having the fog lights looked to be a very necessary option as dip doesn't penetrate at all. Do the fog lights help? I may Ebay some and hard wire them in. Pity Tesla don't offer the service or at least have a pay to enable service.
I’ve had various cars with fitted fog lights and the benefit is questionable. It often depends on the fog… if you are are genuinely down to the point of crawling along at little more than walking pace then the ability to pick out the road edges can make a difference, but giving a longer view ahead not so much. Maybe I’m wrong and the M3 has magical fog lights but I tend to think we’re unlikely to be missing much.
