Yes, tere are quite a few things that prevent it activating on most cars.

I didn't even know my car had it for four years after buying it (2nd hand). Once I kew it had it, after it had activeted to my surprise on one journey, I looked it up. Mine (Vauxhall Insignia 2015) won't activate if you have the air con turned on, or if you have the front screen demist turned on, or if the engine hasn't reached steady engine temperature, or if you have just come off a motorway or similar, or if the battery is not fully charged, or a few other things.

You don't need to keep your foot on the brake to keep it stopped though, when it does activate. Just leave it in neutral and at a standstill (preferably with handbrake on, but that is not necessary for operation). Depressing the clutch starts the engine then.

On mine (BMW 330D 2014) it seems to be mainly if engine is not up to temperature or outside temp is too low. If aircon is running it seems to cut off for 30 seconds or so then starts the engine again.

But, on tight twisty lanes, such as here in the Lake District, it can be over-zealous and can become a real distraction. This is simply a function of how the radar system works.

That was how I found out that my latest car had that function, coming off the top of Alston Moor from where the cafe used to be, down the twisty bit to Melmerby, at first I thought the wheels weren't balanced by the way the steering wheel was juddering. 😂

Certainly on the Mazda, if stop start is active, it will restart automatically after x amount of time (not sure the exact timescale)
I gather the theory is, you don't want the engine oil running back during a prolonged stop, then driving away full beans without full lubrication.
Something I read, which seems to make sense.

Reading, obvs

So does it insist on you warming up the engine before driving off at the start of a journey?

Stop start on the Mazda will not operate until the engine has reached operating temperature (among other things) I think that's pretty universal. (Or have I missed the gist of your question 😉 )

Edited...
Disregard the above, I see where you're headed.
No, its a contradiction to be sure but I suppose if you go full beans on a cold engine...that's your look out your risk
If you go full beans on a warm engine which has been auto stopped, long term damage.may occur and that would be failure because of the drain back) This would be a design problem

just theorising on the basis of what I'd read (engine automatically restarting after x time, regardless of whether you're ready to drive off)

our stop start is brake pressure dependant, hold the brake very lightly (below 5% on the readout) and it doesnt stop, and for most junctions below 5% is fine

which heating controls do you prefer, something modern (and you have to work out how to get to this menu first)

or my old van - don't even have to take my eyes off the road (and I never get cold feet in my van, like I do in our silly car)

I wish I'd heating! My 20 year old Jimny is an ice box as I've no functioning heat coming into the cabin :cold: Nice in the warm weather though :music: actually no, it doesn't have a stereo either!

You'd be hard pushed to see any regular car on the road that has less beeps and buttons. I think the only sensor is the 'you've left your lights on' one.

Disinterring an old-ish thread.

I hired a car on hol and it turned out to have lane assist. Driving along a very twisty, quite narrow, two lane road I clearly did not meet it's exacting requirements and steering became a real battle. It also disagreed with me when I changed lanes to give some road workers space (It thought I should have run them over). It also had an "auto-distract" feature - a constant succession of bongs and pop up messages which I did not read. All in all a horrible experience.

Most can be disabled.

We have ours on for long M'way journeys but off for local twisty lanes.

Yeah but this was a hire car and foolishly I just got in and started driving. When I got to my destination I found there was no manual :sad: At this point the car and I were full enemies and the relationship never recovered.

I can't imagine many people read the manual of a hire or courtesy car, tbh.

Whenever we get a new and different model car to what we had before it takes days to 'move in' properly.

At least you know now to figure out how to switch off lane assist before driving off in similar circumstances in the future.

Under the right circumstances it is a potential life-saver. I know someone will probably post that they have driven x hundred thousand miles and have never once drifted out of lane by even 1mm, but I would find that absolutely astonishing.

Or I could stand by what I said at the time, which went along the lines of ""I hate this effing car and I'm never going to drive a hire car ever again" ;)

On hearing me say that the car bonged and popped up yet another distracting message in French that, had I read it, was probably a sarcastic critique of my driving.

I’m not aware of a legal requirement for a vehicle to prompt its owner at every speed limit change. Isn’t that what looking out of the window is for?

A new EU law designed to reduce speeding and improve road safety will apply to all new cars sold in the European Union from 7 July 2024

What is intelligent speed assistance?
ISA detects the speed limit on roads using a combination of GPS and cameras that are designed to recognise speed signs. It then uses this information to either limit your speed or produce a visual or audible warning when you go over the limit
