Because cranking the steering ratio up high enough to eliminate hand-over-hand will make the car a twitchy, un-drivable mess.
On Another Forum some members are opining that since yoke wheels work in F1 cars, they're fine for street cars. Sometimes, you just can't facepalm hard enough. Really? Professional drivers in competition machinery on defined courses should be used as a comparison for my mother in a street car?
My 2016 Model S 90D does 2 1/4 turns lock to lock. That's actually pretty quick for a street car. My 2017 Acura NSX, at 1.8 turns lock to lock, is almost too quick. Half a turn lock to lock is simply not usable for a street car.
Look, yoke wheels have been around in aircraft for more than a century and in race cars for decades. They're not exactly a new thing. There's a reason you've never seen them on a street car outside of K.I.T.T. replicas.
