My comments are not dissimilar to the ones provided already. I sense that, like me, you like your gadgets and intend to make the most of them!
1. dynamic/radar cruise control is brilliant, but doesn't work in heavy rain. When you first switch it on, a long press of the stalk will enable traditional (i.e. not radar) cruise control which, depending on circumstances may be preferrable.
2. RSA. I have mixed feelings on that one as I don't find it wholly reliable as it can, as mentioned above, pick up random signs.
3/4. AHS/AHB Works very well on straight-ish roads. AHS itself is just brilliant. My frustration is that, as it is speed dependent, it switches off below a certain speed and often when you most need it. When on a bendy country road, the system will switch to low-beam as you approach a sharp bend. On top of that, trying to find the switch to turn it off in a hurry is a bit hit and miss as it sits by your right knee. On such roads, it is best to revert to full manual control!
5/6. LTA/LKA Useful, in particular when driving at night or poor light... or if you know you're tired. Note that the system will only activate (vibration through the steering wheel and/or audible warning) if you cross a line without indicating. Works well in my view, but best on dual carriageways and motorways.
7. PCS is very good and also very useful when parking.
Connected Car is next to useless from my experience.
