Unless you're revving up to 6k to drop it into first gear, your engine braking shouldn't be abrupt enough to matter. Let them get squirely behind you - it is their own damn fault. If you live in a particularly retarded area, then yeah, a push-button would be nice. (I'm just thinking that would be great on my race car... push it 1/2 second before i hit the brakes so the guy behind me brakes too soon )

My other reason for not liking this push button idea... you only have 100% attention to pay... and if you're giving 15% of your attention to the rear view mirror, 30% of your attention to keeping the car in a straight line, 25% of your attention to keeping your car in the proper RPM range, downshifting, etc... 25% of your attention to traffic around you, and 5% of your attention to making sure you are going to be slowed down and stopped in time, while giving yourself enough reaction time to maneuver if necessary, then you try to spend another 10% of your attention to make sure you hit that button every time you notice that someone is behind you while you're slowing down, so that they can more easily tell that you're slowing down, and don't hit you, well, you're now using 105% of your attention, and you're not the US government.. you don't work on credit.

Maybe just a bumper sticker?

Here's an idea...

A 1-axis accelerometer with analog output tied to a comparitor with potentiometer adjustment connected to a relay in parallel with the brake light circuit.

In normal human-speak, a circuit that turns on your brake lights at a particular level of deceleration, regardless of that deceleration being caused by your brakes or your engine or a wall.

I have also considered that this circuit could be connected in such a way to rapidly blink your brake lights in the event of a hard deceleration. I think a few new cars are doing this with their centre brake light (maybe all of the brake lights, but definately the centre one)

I remember back in driver's ed when we talked about manual transmissions, downshifting to slow down came up. The teacher and book suggested tapping the brakes for 1-3 seconds at the beginning of your slowdown to alert a driver behind you of the change, but then just go without the brakes.

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

Sounds a lot like a Tekonsha Prodigy trailer brake controller, it uses some nice accelerometer technology. Don't know how much an accelerometer costs which may be cheaper. Only thing is you would have to leave it on all the time which might drain your battery if you connect it to constant 12v to use with EOC. Or maybe connect it to a timer that will leave it on longer than your longest EOC then shut off. If you don't EOC, then connect it switched with ignition and call it good.

There's nothing wrong with being extra careful.

For one, yeah it would be their fault if someone hit you, but who wants to live the rest of their life with whiplash?! ...in pain, without range of motion. F@#$ that.

Two there are enough people driving like pricks already. Of course it your choice. I'm a firm believer in highway etiquette because I think if more people would practice it we'd all be a lot better off.

I lightly press the brake pedal, I call them fake brakes, if anyone is behind me. I also FAS a lot to lights and do the same.

I do not use the fake brakes on exits and some right turns if I have a tailgater. I love these guys on corners. With my tires to 44# (max sidewall) the Yaris corners great and I can take a corner a bit faster than they expect. I already know just how slow I need to be going and have anticipated it way before the corner by coasting. They must think because I have been going slower on the road that they can just follow me around the corner… Shazam! I make the corner and they nosedive or panic and hit the shoulder. Folks that are back a respectable distance can see the corner and set their speed accordingly, not to mine. It’s not much but gives me a smile now and again.

I kinda do that alot too... I take corners unreasonably fast, since I've spent so much time on tracks and road courses, it doesn't bother me when the vehicle leans extreme... others tend to want to counter the motion, though, which sends them in the wrong direction.

Honestly, if someone wrecked behind me because of their attempts at mimicry, I'd not feel bad at all.
