It's historically been the responsibility of the driver to do so though, not the vehicle.
but also recently historically (?) tech has brought auto wipers and auto lights. Auto lights tends to work on brightness, but if its a bright and rainy day (like last week on a long drive) they won’t come on - so tying it in to auto wipers is a useful additional data point for triggering.
If we’re already ok withhanding off that driver choice to an automatic setting, why not have that be a little more cautious?
I’d be ok with this - maybe bring to all markets but have as a toggle for non-mandated countries?
