I do miss manual when driving on lanes but I doubt I will ever go back and next car will probably be electric anyway.
It wont be long until a petrol car with a manual gearbox will be seen as an enthusiasts vehicle or some sort of classic.
I hate flappy paddle mode though. Utterly useless as my car is so well sound proofed it's hard to hear the engine and without the clutch it feels like a big part of the gear change is missing and you have no feedback on rev matching.
Only time I tend to use them is when I am in super eco driving mood and am making the box change up sooner or if I want to overtake but not use the kickdown or press the sport button. When it's in sport mode it can change gear far faster than I ever could anyway.
