so to have this means you need to specify either lane assist with dynamic light assist and traffic sign recognition costing £630.00 or lane assist with dynamic light assist/traffic sign recognition AND rear traffic alert plus traffic jam assist for £1225.00
On the old Mk7 options, to get the dynamic lighting you needed to spec the lane assist option, so this isn't new really.
I think the reason being is that the camera unit which looks for the white lines to follow also is the same camera unit that is used to detect objects for the light masking feature. Its also the same camera used for traffic sign recognition BUT a different camera used for the (old and not available on Mk7.5) High Beam Assist.
When the Mk7 came along this point was extremely unclear in the options brochure - the actual dynamic lighting system was a showcase technology for the Mk7, yet how you actually ordered it was a mystery to most.
Still, in 3.5 years they haven't learnt that lesson at all...
