I am on a couple of car forums and the norm there is to curse the stupid thing and turn it off. But perhaps car forum users are more savvy about things like the load on their electrics and more capable of deciding these things for themselves.I generally leave that decision to the stop-start facility of my car, and I suspect these days that's the norm. This decides for me based on things like load on the electrics (e.g. if the fan is on) and on the battery's charge level.
Anyway, I don't suppose your start-stop facility can see that the traffic lights ahead are about to turn green anyway, and you will need to move again in a couple of seconds, nor that where you have stopped is in the middle of an intersection and a very dangerous place to be if that 1-in-1000 chance of not starting should turn up (see my post above about batteries dying suddenly).
