The Auto Stop-Start doesn't kick in when:

1. Outside temp <3C or >30C with switched on A/C.
2. Interior temperature not yet attained (i.e still heating up or cooling the cabin)
3. After driving in Reverse.
4. Battery is not fully charged
5. Engine not yet operationally warm.
6. Defrosting is in effect.
7. Stop & Go traffic
8. Engine bonnet/hood is unlatched.
9. HDC is activated
10. Large steering movement

Also, the driver can prevent the Stop-start function on a case-by-case basis. Immediately after the car is stopped but before the function cuts the engine, forcefully pulse/push the brake pedal to the floor then quickly release.

Do y'all read the owners manual?

I don't understand the fear of wear-and-tear on the engine. BMW has used this in MT cars in Europe since 2008. The starter and alternator are especially designed for this kind of operations. I do stop-start on my 2004 X3, and after 116.800 miles (188.000km) the starter still works fine. Considering I just replaced my first battery back in July, no real effect on battery life either.
