My Corolla, with a very modern and efficient engine, uses almost no fuel idling at the lights. So I switched it off.

Another reason is I don't want the battery to prematurely die, which is bad for the environment.

M2 has it. I love it. It means being in neutral at a light. So I play a game where I time the light, my shift into gear, and my clutch release to all come together perfectly.

A rental we drove for two weeks in the UK hhad start/stop. It wasn't mentioned to me when we took delivery of the car(Heathrow), so the first time it shut off the engine, in a tailback on the M 25, it was a bit unnerving. After that, no big deal. If I had to spend a lot of time stuck traffic, I would welcome it.

I’ve got it in my E Class and HATE it. I wish there was a way to permanently disable it rather than every time you start the car.

I’m not comfortable with an aftermarket solution since I’m still under warranty.

I wonder how much fuel this really saves.

All of our water cooled cars have it.

Fortunately I was able to turn it off on my 2014 Cayman 10 years ago and it's stayed off ever since. The Panamera has to be turned off every time we drive it. The Tundra seems to only shut off when I put it park which means I often think I've already turned it off so I get out only to find it's still on :mad:

I've driven a couple/few cars with it. I don't like it either.

I am/was surprised that the 2018 Outback that we bought a couple of years ago didn't have it.

It can often/usually be disabled, whether via some sort of button/switch or a light foot on the brake pedal or whatever.

I was listening to a Jason Cammisa review of the new M2 - apparently the lane assist (even more annoying than start stop) is always ON at startup and requires a deep dive into submenus - each time - to disable... Not even a button, nope... Manufacturers don't listen, probably because their cars are rare right now and we keep on buying like lemmings, out of habit - oh's it's 3y old, need a new one!.. Cammisa said he would return the car and sue BMW if it was his ;-) I agree with the sentiment. Turning into a grumpy old man here but maybe I really should hang onto my old cars.

On a similar note, Porsche has made stupidly long geared manual cars for a decade now, same reason - kinda hard to get anyway, selling all they can, so why listen to us and make a non autobahn ratios... Also they decided to charge +10-15% on new cars next year - just because they can - not to make up for any specific supply increase. All manufacturers figured out during COVID that there is more money in producing less (less costs, less work) and charging more, they are taking their slice out of the "dealer markup". Why make 5 cars when 3 will net you the same profit and increase rarity ? Again, as long as we keep buying (and there's enough new $ out there for that to happen), it's never gonna get better. Hang onto what you like with as few "screens" and "eco-nannies" as possible.

I sold my 991 for the same $ as my purchase price after 5.5 years (of near free usage!) and felt like a genius for a few months...now I am starting to regret the move because I realize they way things are going, I will likely NEVER own something like that again - between the way they're bundling them with all those stupid undefeatable features and upcharging for them - and forget any GT car unless you are a VIP. Oh well.

it's not about the car owner saving gas. It's about thousands and thousands of gallons per year being saved by all of the users.

But I don't like it and would be concerned with wear and tear on the car.

I think this video may address it.

It's not about saving the individual car owner money. It's about the cumulative effect of thousands or millions of cars over time.

My van has it too. I haven't gotten around to turning it off, expecially since we live outside of town so it doesn't cycle nearly as often as it would with town driving. I did read in the manual a comment that the battery and starter were disigned for that feature.

There are plenty. My GF has a new Malibu with no way to turn it off. It is the MOST annoying thing. My BMW has a switch that has become part of the start up routine and my new Tacoma doesn't have it, thank jeebus..

It all started with Harley Davidson..

Not sure if this is true but a friend told me his Uber driver told him that if he opens and closes the hood after he starts the engine, it cancels the auto-start. A pain in the butt to do over and over but if you keep your car running for hours on end like an Uber driver, it's a good work around.

Nice.

Sounds like one (hood) sensor input controls... That should be easy to make permanent.

Ours has an auxiliary battery to run stuff when the engine is off.

Efffin efffin modern vehicles trying to out-think the driver and force upon them "safety features"...

Which are supposed to make us more safe...

I drive with the dog or groceries in the passenger seat.
And at the worst moment while trying to check corners and not cause an accident, another loud chime goes "Bong Bong Bong Bong Bong".
The dashboard might as well turn into a disco club.

Had a rental Jeep in Hawaii with the start/stop feature.

didn't like it at first, but helll it's just a rental for a week so could live/adapt to it.


don't think I'd like to rely on that system, maybe it's growing teething pains.

just like auto-lane-centering steering . ugggg, no thank you.

I have no problems with it on my Civic.

Try it for a while...it's hardly noticeable.

You can turn it off with the push of a button in my truck (2021 Chevy Silverado).

Maybe Honda came up with a way to make it less obtrusive, but that is not the case in any car I have driven with it.
