The Taycan freewheels when you take your foot off the accelerator and only regenerates when you hit the brakes. This is quite different than most other electric cars.
That's just a default configuration difference. You can configure it to do lift-off regen if you like. There's also a camera based auto-regen mode that can switch between coasting and regen based on the distance to the car in front.
Philosophically, Porsche believes it's easier to drive a car fast when one pedal is solely responsible for accelerating and one for braking. Having the throttle be responsible for acceleration and light braking makes it difficult to modulate speed consistently. You can even see the philosophy at work on their gasoline cars, in Sport+ mode the anti-lag system pretty much removes engine braking.
