EV Retardation - Dangerous?

[the cueball]

I've tried a few EV cars over the past month (I3, Model 3 and Ipace) and they all put the brakes lights on when in regen.

I seemed to have an "easier" time adjusting to the 1 pedal as I ride a bike, so I'm very used to using just the throttle to go n slow.

TBH, I try to do it with my ICE cars too...

Looking forward to changing over to EV once the numbers make sense to me...

The brake lights come on once you slow down faster than pre-determined re-gen rate. In over 50K of EV driving I've yet to have anyone crash into back of me.

I borrowed an i3 for a day and thought exactly the same GMG. Whereas I’m used to seeing traffic ahead, taking my foot off the accelerator to slow to match their speed by the time I reach them, with the i3 it was difficult. It was either take my foot off, experience rapid retardation with the brake lights activating, then correct with accelerator, or get the timing right, driving up to them then letting off with the same brake lights. Either way it was too much brake light for me. Yet it felt unnatural to feather the throttle to slow without brake lights - a fine balancing act.

Maybe I’d get used to it but it bugged me.

Unlike in an ICE car, you don't take your foot off the accelerator completely when trying to come to a gentle stop, you modulate the position of the accelerator pedal to get the desired amount of regen braking. Brake lights do come on.

Once you get used to it, having to use the brake pedal to stop in an ICE car will feel archaic!

The lunacy of how the EV brigade express things, no wonder it always turns in to a punch up

TX.

And of course words like "lunacy" and "brigade" don't feed that fire, do they?

I've an EV and an ICE, I can confirm that it does feel archaic getting in my ICE after driving the EV. ICE is a technology which is becoming obsolete, and in comparison to the latest drivetrain types it is indeed old-fashioned.

Sorry, Grandad.

The chap could quite easily have just said different but chose archaic so yeah no wonder it is all sweetness and light in the EV section. Obsolete though or indeed becoming obsolete, you are deluded.

Haha, some people just don't like change.

Likewise some may consider you a sheep given you follow blindly with the latest "thing"? No doubt you have an Apple phone too and update it every 6 months, presumably if anyone dares to use something different they don't like change either? EV's are being pushed with tax incentives and legislation and even then virtually no one buys one vs petrol or diesel but yeah you go ahead with your blinkers on.

Wowee, not much of a snowflake are we, taking umbrage at that word. Blimey.

You carry on, though. I know where the delusions lie.

Oh, and if you don't want a fight, don't be overly sensitive to innocuous comments, and don't respond to them with escalating insults.

If he doesn't do that what else is he supposed to do with his time?

Just to confirm, I've also used the archaic expression more than once. Describes the experience perfectly, especially for ICE cars with a manual gearbox.

Doesn't mean I can't still enjoy it in the right circumstances though.

Of course. I still enjoy my ICE car too. Doesn't mean it isn't old-fashioned and near obsolete. A pony and trap is archaic and obsolete, but I'm sure it'd be great fun. The world is not binary.

Using brakes just feels so wasteful after one pedal driving an EV

[citizensm1th]

One wonders how the op copes with sharing the road with hundreds of hgv, s that have exhaust bakes that also show no warning of a hgv slowing down

[anonymous-user]

You do get used to it as the driver

On the i3 the brake lights do come on when the driver is off the go pedal

[anonymous-user]

......and yet another thread dissolves into puerility.

Well done children.

You're just annoyed you didn't get in first.

i jumped in on an early outlander, and it didn't light the brake lights despite some pretty dramatic deceleration when the battery could take full regain flow. not emergency stop dramatic, but way more deceleration than moderate brake pedal usage would provide. brake lights over a certain -g detected would surely be easy peasy these days?

No, it is simple. I posted a link to the product on page 1. God knows why manufacturers did not do it right away.

How do you know the brake lights aren’t on?

In my i3 I can see the brake lights illuminating road signs and vehicles behind at reasonable regen levels (around 1/4 onwards on the display at the bottom). If you’re not getting similar I’d suggest there was something wrong with your car.

The i3 definitely illuminated the brake lights on reasonable regen braking.

IIRC the Outlander shows the brake lights when using the higher levels of regen.

I believe it is only on newer models

My 2014 did it.

Legally I think its set at 0.2g deceleration, though not sure its that in all markets.

Try no to drive up someones arse and it wont be a problem..

This. Also try not to use the throttle pedal as a binary device and it's unlikely they'll light up anyway. Very easy to modulate the throttle input in order to slow down at a similar speed to backing off in an ICE vehicle in my experience.

Yes, imagine the "victim" stabbing herself with her eyeliner because she plowed into the inconsiderate bd in front of her.

PS: Nearly all modern EV's will light up the brake lights under heavier regen. Unlike in manual cars, where you can engine brake fairly hard without lighting up the brake lights.
