This situation is kind of annoying though when you follow a manual driver holding a steady throttle and they slow so much on their gear change that you quickly gain on them and have to lift, sending your shifting rythm out of whack. First world problems I know.

Slightly going OT here so apologies, but I've noticed it a fair bit now people who drive electric vehicles have regen? I hope that's the correct term where the car uses the breaks to slow it down automatically? Few times I've nearly been caught out coming to slow moving traffic as it does not activate the break lights?
Or I'm just probably taking a load of rubbish sorry.

You can get the same with engine braking in an ICE vehicle - if I'm in sport and decrease speed beyond a certain rate engine braking kicks in and will continue to slow me rapidly even if I come off the brakes, without the brake lights on, unless I get back on the accelerator.
Yes, that's sort or right, it uses the motor to put charge back in to the battery which also has the effect of slowing the car down, depending on how heavily I lift off the accelerator in my Model 3 depends whether the brake light comes on or not, in steady 30mph driving it will come to an almost stop before the lights come on.

Certain deceleration does legall require the brake lights to come on.

I see thanks
have you noticed if it's caused you any issues close calls? Really tempted to try a Model 3 long range when I sell the Giulia possibly next year.

That's what I thought - when driving the iPace with full regen (so single pedal driving) I hope it put the brake lights on!
As a quick aside I loved that car - shame that it was the director's and not mine...
I don’t really understand this. But engine braking will never match regen. Regen can do 0.3-0.4G which is similar to a car actually braking. If people are struggling with engine braking then I suggest they are following far too close
we'll be discussing automatic braking soon.
As a manual driver ... if someone's right behind me/too close, I'll tap the brakes before using engine braking,
hadn't occurred to me before, but perhaps many of the brake lights I see at bends, where I would engine brake, are from automatic drivers (not using paddles) ?

You'd probably hit the back of me then, 4l with treacle for oil means the engine braking is quite severe.

I see
it's just my early morning brain! Most of the time I'm in auto pilot, don't even know how I manage to get to work. I just arrive!! Definitely not too close, just strange seeing a car slow/stop and not see the lights, never had an issue with engine braking but them electric vehicles stop much quicker when doing regen braking?tesla regen deceleration ->
rules
... so, was this why they removed low mode on tesla ota upgrade.

Yeah I have no idea what kind of Gs engine braking will do but last couple of vehicles I drove it was not insignificant - my truck especially will bleed off speed rather quickly with it.
Are you sure that this isnt mainly due to its aero? Automatics generally dont engine brake much very much at all, but big slabby trucks like yours (or my old RR for example) would slow down very quickly from speed anyway, i always thought due to their very lossy 4wd systems and similar aero properties to that of a bus?

You're all forgetting that Rroff is the worlds best driver, self proclaimed in far too many posts to not get called out on it 
Exactly.
Newer automatics will employ engine braking a fair bit in sports mode and/or other driving profiles where it might be appropriate. In normal driving mode it rarely engages but will under certain circumstances. There is a huge difference to how it rolls off speed normally due to friction, etc. and the effects of engine braking.

I find it curious you would come down on the side of people who drive with lacking consideration for others at best dangerously at worst.
That seems intentionally trying to be hurtful I'm not sure why. My 120MPH was a relatively off hand comment and at no point did I make any claim as to whether it was a big number or not - it will factually sit at 120 odd MPH though
I think some of the posters making the last few comments should take a long hard look at themselves.

Why would engine braking be better in sports mode? 
In response to Roff. The gearbox will simply be in a higher gear in sport mode so when you lift off engine braking it higher.
it doesn’t just ‘turn up engine braking’.
Higher revving engines with lighter flywheels and high compression will have more engine braking than something like a big flywheel diesel (diesels have less braking as they are without a throttle too)
