Pedestrians, shops, residents, offices all benefit. My two cars do hundreds of ASS cycles a day with no annoyance to me, and if using it per manufacturer design makes it fail, it’s warranty.
but not everyone lease their car. I usually replace my car every 10 year in average. my last car serve me for 13.5 years.
continue stop/start put a lot of extra wear.

I guess if a driver sits at a light for a fair amount of time the ASS is not that big of a deal, but stop-and-go would be very annoying and also wear components faster.

I agree with just hitting both the start and ASS button simultaneously.

Well, me too. My son is 11 and I expect heíll probably learn to drive in this car. If anything the car will have worn less by using ASS.

Not only does it reduce your fuel consumption it also is almost unnoticeable when it kicks back in as you pull away. I've not had one situation where I wasn't able to put my foot down and go from a standstill and be hindered by the stop/start system.
I don't agree. It's very noticeable to me. Another problem is the air conditioning stops running on a hot day and you can feel the moisture build up. It kicks itself on eventually if it's warm enough, but neither of these things are something I want as part of my luxury car experience.

Again as a general reply, in addition to liking and considering ASS as an emissions and local pollution benefit, Iím not saying it must be used 100% of the time. The car wonít use it in sports mode or sports shift. Good. The HVAC moisture build up only happens in Eco mode as it delays a bit longer to kick back in for cooling. Makes sense.

Just like I occasionally turn of recirc, or the HUD, I sometimes might also disable ASS for a specific situation. But most of the time (on our BMW and Subaru) I completely ignore it. On both cars, my wife doesnít even know where the buttons are.

Everyone has the right to disagree or may have very specific situations but I make these posts for the benefit of people who perhaps are considering whether itís a bad thing as part of making a purchase decision or even, as some people are suggesting, bad for the car. It isnít.
