EV Retardation - Dangerous?
Discussion
I've seen many electric cars on the road and I'm aware they have higher levels of retardation (setting myself up for something here I feel) due to their regen systems but last night I was following a brand new I-Pace and then drop off in speed was crazy. I felt like I really had to be on my toes when following in traffic.
It was night/raining which didn't help and I know some of you will say you should focus on the car in front of you all the time but you know how it is really.
It was slowing down a lot faster than it would've if they used the brake pedal in a normal fashion which got me thinking it wouldn't be a bad idea to have a small flashing red light when slowing down under the regen system a bit like the ERS charging light in F1.
I felt like it was asking for an accident when someone who sits on their phone/does make up etc in traffic are following.

One pedal driving, seems to be me, smoother and safer way to slow down a car.
I understand the deceleration curve is computer assisted? So a small update could fix it.
Not sure about ipace, but tesla regen braking is recently updated and is now very smooth.
Also the brake light is designed to emulate ICE behaviour so ideally you shouldn't notice a different.

In the i3 it looks like I’m riding the brakes all the way down now, when just using regenerative braking.
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 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?
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.
