EV Retardation - Dangerous?

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.
I'm not saying they weren't on - on the contrary, I'm saying there's too much brake light activity with EV's (after 20 years of stepping off the accel and having speed gently wash off with an IC), and I've always associated too much brake light with bad driving (the concertina effect on motorways for example). I'm sure it's just a learning process, and I tend to think Shaoxter is right, but on the day, with a borrowed i3, it irked.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).

There is a long downhill section of my return commute and in my ICE car I’d just stick it in a lower gear and use engine braking pretty much all the way down. The incline was such that the car would hold at the speed limit nicely.
In the i3 it looks like I’m riding the brakes all the way down now, when just using regenerative braking. Intuitively I feel like it looks like I’m a worse driver than I actually am, because I always used to roll my eyes a bit at people in front of me that didn’t have the ability to realise they were in the wrong gear, always braking to slow the car down, etc. I was taught in driving lessons to use engine braking to slow the car down.
Unfortunately I think that’s just the way cars are now. I don’t judge people who appear to be sitting on the brakes at traffic lights etc when they could just pop the handbrake on anymore, since it’s entirely possible they don’t have total control of when the brake lights come on anymore.

I do wonder about future problems when people only used to one foot driving, over many different cars, suddenly find themselves in an archaic ICE hire car on holiday. will it be coasting into the car in front or panic braking catching the car behind out?
Could be, but at this point even the "one foot driving" isn't consitent enough.When the battery is too full or too cold for example, it's nearly non-existant.

I don't think you can judge much on just a single day.Edited by DDg on Thursday 12th December 09:40
I rented a Tesla S 75D for a weekend to go from Manchester to Cheltenham and back, as it turned out to be a lot cheaper than expected, and on the first day I struggled to understand what all the fuss as about. By the end of the weekend I was loving it - it took quite some miles to adapt my driving style to suit it. I would love to spend more time in one, but the want is much stronger than it was.
The Autopilot is still questionable, especially when surrounded by other traffic - it feels unsure and has the odd panic brake which on a couple of occasions resulted in me being on the receiving end of some vinegar strokes from drivers who were driving too close behind me in the roadwords at 40/50 mph..
I find the OP's suggestion that EV regen braking is dangerous as other drivers following too close may not be concentrating strange - how is this any different from following car that has to do an emergency stop?
Full autonomous driving will only work when every car has it - and then hopefully the poor brain dead drivers who do not want to take responsibility for their own carelessness will no longer have to worry about finding someone else to blame for their stupidity,

Nope, the brake lights on the i3 are triggered by a level of longitudinal decceleration and not in any way by pedal position. If they are on, you ARE slowing down (at above about 0.25g) so if you are doing that continuously, then you'll stop, obviously!!So, you lift the accelerate to the point where the car is maintaining a constant speed and the brake lights will NOT illuminate!
(and once you get used it it, which only takes a few days, you quickly get used to having just one pedal to drive the car, and it quickyl becomes not only easier, smoother and safer, it suddenly feels like two pedals is the stupid way when you get back into a conventional car.

I get that already going from a Leaf 30 to an ICE. I used to drive in B mode (max regen) all the time.RobDickinson said:
If you are driving an EV using one pedal and binary treatment you will quickly make your passengers throw up anyhow...
True. My wife and I tested an e-Niro and ordered one. We went back for a second test drive when I did all the driving using full or auto regen.
When we got home my wife was having second thoughts because she’d felt ‘thrown about’ and queasy.
I’m sure it was to do with my unfamiliarity with 1 pedal and it’ll get better; also she’ll not notice when she’s driving.
We’ve made our concerns known and are getting another 24 hour test in January to resolve things.

tbf tesla model 3 regen was jerky and unpleasant in Oct, but it's basically silky smooth now. So might be worth research eniro's update options if regen is a deal breaker.
It won’t be a deal breaker. For one thing we won’t get car till August and it will be the fully upgraded 2020 model. May or may not be better. Also, the range, even not bothering with regen, will be more than enough as a second car so it’ll get set where it doesn’t give any issues. From memory it has 4 settings + auto.

We test drove a kona (so very similar) and both felt car sick, I'm usually unaffected.. And know how to drive an ev. We went back for a second test drive when I did all the driving using full or auto regen.

Never been a problem in the tesla
