No Physical Drive Mode Selector?

The Polestar has something very similar but it is selectable on the control panel vs the shifter. You can have full regeneration, partial regeneration, or very little regeneration. If you put it on full you will have the same one pedal experience you have in the Bolt.
And as for the brake light, regardless of whether you are using one pedal driving or the brake pedal, if the car begins to slow beyond a certain g-force, the brake lights will come on. I know it works this way in the Bolt, and I'm fairly certain it's the same for the Polestar. And just like the Bolt, the Polestar brake pedal uses a blended system of regen first and then friction brakes.

Yes, it's on the screen. The Bolt is software controlled also, but you activate it with a physical stick by going into L mode.
I agree that in D it's unlikely that the brake lights will come on, but they are not only activated by the brake pedal itself but by the amount of negative g's. I'm not a huge fan of one pedal driving and usually leave my car in D and so may set the P2 for minimal regen. What I have become used to is the regen paddle but the P2 does not have one of those. Maybe I'll get used to one pedal driving at some point, but it's hard to teach an old dog new tircks.

I will miss the regen paddle too. But if I can't do without it then I can't drive a P2 🙃
I can assure you that every EV out there activates the brake lights when regen hits a certain negative g-force without regard to the brake pedal. The same is true for ACC systems. The brake pedal will also activate the lights, but just think for a moment if you could do significant regen (via paddle, L, one pedal driving, ACC, etc.) without the brake lights activating. Accident rates would skyrocket, and the government has mandated it.

Not only am I an EV driver, but I've driven a Bolt on many occasions. I think what you are looking for may be unique to the Bolt, or Chevy. Chevy did a number of things with the Bolt and Volt to make them as similar to an ICE car as possible. Those were marketing decisions from 10 years ago. But that's not the general direction of the EV market today. And my suspicion is that you are unlikely to find it on newer cars, particularly higher end ones. Hyundai and Kia have some capable EVs that compete directly with the Bolt, and you might want to investigate if they have this unique feature.
The Kia Niro EV (and I think Kona EV too) has paddles to control level of acceleration and level of braking on the steering wheel itself - not unlike paddle shifters on sports cars.
I admit I wish something like that was on the P2. Would be great if one of the steering wheel buttons could be repurposed for this or if the gear selector could be used.
Having to touchscreen this is not ideal - although I think it's just two taps, one to get to the drive settings, and another to hit the braking setting.
Voice activation for this switch seems cumbersome, although I guess I would mainly be switching from one pedal operation to coasting on the highway and back to one pedal for the city or suburban streets.

I usually leave it in D and use the paddle. But only with the brake pedal can I completely and smoothly modulate deceleration.
Also, note that braking with the P2 (up until a pressure point) does increase the regen strength rather than invoking the friction brakes (some other EVs only use friction braking entirely). So you can still increase regen but it won't be with one peddle driving.

I think this is a must, and if I'm not correct, Tesla does not have it.

The P2 has blended brakes just like the Bolt. Most of the travel does not engage the friction brakes at all. Only at the bottom do the calipers engage the disks. I find modulation on the Bolt to be fairly easy.
The calipers don't do regen (on the P2 or the Bolt). All the regen is done with the motors with software blending in the calipers only as necessary to generate the stopping force your foot is requesting.

The sw blends the motors with the calipers. Those are the 2 braking components. The pedal first engages the motors for regen, then as necessary (through a sw algorithm) the calipers are engaged for friction braking.
Motors do regen. Calipers do friction. The software blends the two based on pedal deflection and pedal engagement speed.
