Nit: Breaks do change because of regenerative breaking.

Nit: Brakes (you both made this mistake)

  Sometimes I also misspell words out of a misguided sense of solidarity. It's like having a conversation and someone keeps mispronouncing a word. Do you just imitate what they are saying and avoid correcting them or do you tell them they are wrong?

    Your right. Sometimes its nice to give people a brake.

      That’s your view and you’re very kind.

Nobody in this thread can spell brakes it seems. The regenerative braking is done in the electric motor, not the calliper/disc. Nothing has changed there.

  When you push the 'brakes' on the an electric (or even hybrid) you simply engage the electric motor. There is a limit to how strong this form of braking can be so in certain cases you will need emergency brakes (disks or otherwise). So the brakes on an electric vehicle would be very different. I would guess in the future they wont even exist. It will just be the motors. Motors to wheels so no drive train either.

    Sounds to me like the brakes would be exactly the same. The wheel is connected to an axle and has a brake disc. The fact that the axle can slow the car isn't any different than exhaust braking, for example. In case you're thinking the hydraulics would have to account for regen braking, I'm not so sure that's true. In my Tesla the brake pedal only controls the brakes. Regen braking is done by letting off the accelerator. You can't always use regen either btw even if it was powerful enough. If the battery is too cold or is fully charged it can't be used much if at all—that energy has to go somewhere.

      We're seeing lots of competing ideas about regen braking interfaces and I'm curious which will win. Tesla is riding hard for brake pedal == friction braking, which is certainly conceptually simple. Lift off accelerator and you get regen braking. Press brake and you get friction braking. Tesla did take away the options about regen strength (at least on my model 3) and now it's only highest. I bought my tesla this winter and it was extremely noticeable how much regen was affected by a cold battery. I had to be very careful not to assume too much regen and after a whole spring/summer/fall cycle of consistency I'm slightly worried about being too one pedal complacent. Hyundai/Kia has repurposed steering wheel paddles to add or remove regen strength on the fly and now ionic 5 will dynamically adjust the regen using the front facing cameras to slow you down as smoothly as possible. Most of the euro brands are all embracing D/B modes on the shifter, with D being limited or no regen and B turning it on (and often with strength settings from there). Porsche has gone full blend, with the ability to freewheel the rear axle and only the brake pedal being used to slow down. The first amount of travel is regen only, then they slowly blend in friction brakes. I'm sure there are other patterns out there. It's been a long time since something so fundamental to driving has been open for new concepts, so it'll be interesting to see what wins.

        Yeah I've had my Tesla for a couple of years in California and even in our mild weather the seasonal differences in one pedal driving are something you have to pay attention to. I haven't tried the other methods, they sound worse to me but perhaps I'm just used to the Tesla approach.
