Regeneration in non e-tron Vehicles
I am coming out as having never driven a Tesla. I've owned countless cars including 3 EVs but never drove a Tesla. The cars seem good but I am a car guy since childhood and got a weird feeling about Musk in the Roadster days, and then the fan boy thing happened and I just steered clear based on the grifter vibe. No shade, just my choice. In any case, I believe it was @JNealCox who recently mentioned in another thread that Tesla does not have a blended brake system. That is, you press the brake pedal and it's 100% mechanical.
One of the things I like most about the e-tron is its innovative energy recovery and regeneration strategies.
I did some research on Mr. ***'s obvious mis-statement and the results aren't what i was expecting. Please someone, tell me the world's most valuable car company's constantly-hyped-in-my-face technological advances include a blended brake system. You know, like my 2004 Prius had, where you step on the brake and it uses regeneration instead of mechanical brakes, and then blends the two as needed.

You are not allowed to mention it on the Tesla forums, but there is an entire theory that the so called "Tesla sickness", the motion sickness that Tesla occupants but not the driver often experience is actually caused by one pedal driving. It was first thought that people were not prepared for the acceleration, but more data seems to indicate that people really are not accelerating that often, but they undergo the constant acceleration and slowing down YoYo effect. The driver does not experience it for the same reason that drivers more often than not do not get motion sickness. They are prepared for the inputs and don't feel, or might, even anticipate the YoYo.
I am not crushing Tesla's. This is just a theory that is bandied around on Tesla boards before the crazies crush it. Apparently, coasting, flattens the YoYo out.

Tesla is the only EV company at the moment that does not utilize blended braking. They prioritize lift off regen as their primary form of regen. The brake pedal as already mentioned is mechanical braking only. This has been there since the Model S so you can blame Rawlinson, the guy who actually worked on the Model S. I have no clue why they have not gone to blended braking.
Early blended braking generally had a very poor transition so maybe Tesla couldn't get it to work and just went full out on lift off regen/1 pedal driving as their schtick.
I'm also a fan of coasting. When I first used it, it felt like the car was still accelerating/running away and I took my foot off the accelerator. Now, I'm use to it and also can modulate the hand pedals pretty well.
My wife prefers to keep her Kia Niro EV at regen 1(the lightest) which simulates engine braking and use the brake pedal to more aggressive stops.

Wow, so it's true? TIL something new. TBH, I could live with mechanical brakes and a paddle for regen in a basic EV. I assume Teslas have paddles for regen.
There must be some other PHEVs or hybrids or EVs that have fully mechanical brakes and you can only regen from a paddle or via one-pedal programming.

Tesla is into the 'minimalism' [cough cough...cost cutting] thing. So no, they do not have paddles for regen control.
You're lucky to get a signal stalks or a gear shift selector...oh wait...thats missing too...another feature,

I have never understood the paddles thing...NEVER use it...but I do like the coasting and blended braking.
I've never heard of the Tesla Sickness that A4Phil mentioned, but it makes a lot of sense. I test drove teslas a couple times.... liked it ok, but coasting makes so much more sense in my thinking...and I can understand the idea of that motion sickness. It's not smooth
My only wish in my Audi system is I wish that there was a better indication of when the mechanical brakes are being used and by how much.

Different cars work differently, Tesla's DO coast you just learn to use the pedal to accomplish it, and tesla braking can be modulated by the pedal as well, which is why I think the idea of "Tesla sickness" is silly FUD. One pedal driving isn't stop and go with nothing in between. You learn to let use the accelerator the same way we learn to feather the brake pedal to gain more efficiency on stops. Its not a big deal, but I can see the convenience of it and why many enjoy it.

I find the paddles to be of limited utility. When I use them (which is rarely), it's when I'm going down a short hill and need some drag to keep from accelerating. But I'd say more often than not I end up just using the brake pedal, since I can better control the amount of drag that way. Using the brake pedal for this was something I had to make myself do, because of course standing on the brakes down a hill is a big no-no with friction brakes. If I'm going down a long hill, it means I'm probably on the freeway, and that means I'm probably using cruise control, which does a much better job of managing regen than either the brake pedal or the paddles.
If Audi eliminated the paddles on the steering wheel I would barely notice.
