The car is still a month away
The car is still a month away from delivery, so we do not know details of how it will work. It could be that the steering has a variable assist that turns the car's wheels more at slower speeds, so that making a U-turn would just require a 90 degree rotation, but at faster speeds there would be less and less gain/assist. But I'm just guessing here. Performance does relate mostly to driving the car yourself, but having more power could help with auto-driving as well, just not very often. Generally for a commuter car, you want comfort and economy. And for FUN you want performance. With most internal combustion engine cars you have always had to make the choice between maximum economy, performance, or comfort/luxury. But EVs can allow a car to provide maximum economy for commuting, along with comfort, and also have the convenience of auto-driving functionality. And then when you want to drive the same car yourself (for FUN) then you will want to access the car's abundant power. For dedicated, fully autonomous (RoboTaxi) vehicles that won't have a steering wheel, they only need for the power to be ample, rather than outrageous. For the cars that we are seeing today, autonomy is not complete, so the steering wheel cannot completely go away yet. And for most cars, I don't see it going away at all.
