This is actually on some European cars, only with the caution lights. I've also seen people turn on their caution lights manually to simulate this.

Christ: I understand your concerns about the extra attention. There are more important things to do while driving, and when those things come up then I'll probably pay attention to them and forget about the manual switch. The brake lights will come on anyway if I really have to brake. If I just forget to push the button while engine braking then it's the same as now. Button pushing will happen only when my processor isn't overloaded and can handle one more thing to do. I do admit, though, that there is a larger load on my processor each time I have to slow down and make the decision: brake pedal or engine brake? If engine, then which gear? Etc.

EDIT: This is my 307 post, just like my Peugeot, a 307 model
