Annoying 'helpful' features on C4 Picasso - Stop/Start and auto parking brake.

I'm not getting how the stop/start is triggering for you at give way junctions.
In a manual car, the Stop/start should only operate when when the car is very close to stopping with the car in neutral and the clutch out.
This is not normal driving behaviour at junctions.

In my car if I'm stopped at a junction and auto-stop has kicked in, if I press the clutch pedal the car engine starts. If I release the pedal whilst still in neutral (and PB still on) the car engine remains on - it is a one-time thing until the car has been put in gear and is moving again.

Risk the car rolling away because you don't want wear on a system that will outlast your car. 
Not all stop/start is the same, mine doesn't kick in unless you put it in neutral and are stopped. I like it and use it as much as possible - I believe 8 seconds stop time is the minimum needed for it to save you vs the engine running so it's not like you can't use it.

No risk - our drive is level, and I always leave the car in gear.

My issue is merely that it is no effort at all to 'manually' apply the pb with a flick of the switch when you want to, just like you do when stopped at lights. Far easier that, than going through a daft on/off sequence with the engine button when - for good reason - you might not want the pb applied (like when parking up for a week or more, or when doing work on the car).

Also, when applied, it's done p-d tightly - full on. The lever equivalent would be to haul the hb up until the cable went 'twang'! It's no wonder it releases with an audible - and physical - clunk each morning. Come on - that is just nuts.

As for the S/S, yes, mine also requires the car to be in neutral and near-stationary (I notice it'll conk out just before if I coast to a halt...). That's the problem, tho' - it'll do this every single time whether it's for one second, 2 seconds, a half second, at a give-way, when clicking on your seat belt - every bludy time. Sorry - that's nuts. And the half-to-two-second scenario is the vast majority.

And, as I said, whenever I approach a light that's only just turned red, I often kill the engine anyway - job done.

I don't have problems in my car, by the time I have put put the clutch down and put it into gear the engine back up and running and raring to go.

Yeah, I like being 'raring to go' too when joining the A39 on a straight stretch. And a 'stalled' engine is not going to have me nipping out into the small, fast-moving, two-way, simultaneous traffic gaps that appear all too infrequently. So - I need to ride the clutch for how long it takes, or I disable the system.

That's nuts, man.

All I'm asking for is the option!

Ah! That could well be true of mine too! So all I need to do is 'pop' the clutch briefly each time and the car will remain running from then on at that junction?

Thanks - that's certainly a lot better

Hang on - the park-brake also has to be on? Aw maaaan :-(

Eh? Car in neutral and foot on brake pedal is not normal behaviour at junctions? What, then, is?

Car in 1st, foot on clutch, hand on handbrake, right foot tickling throttle.

Then to go it is mash accelerator to floor, lift up clutch, drop handbrake and fight the torque steer with one hand

Various lights flicker on the dash as the "drive itself" stuff does its thing.

That's my other pet hate, tho' - 'riding' the clutch.

No, it's not.
At a give way junction, there's no way neutral should ever be in the scenario - you should be ready go (gear engaged, clutch in).
As an aside though, your stop/start shouldn't trigger unless the clutch is released in neutral.
And neutral with the clutch released is definitely odd at a give way junction.
If your S/S is triggering in neutral with the clutch pressed, that's something I've never ever come across and I drive more cars than most.

Sigh. You've clearly not tried to join the A39 on a fast stretch. Sit there in gear with clutch depressed? For how many minutes, exactly...
