Because we’re not talking about car to car, we’re talking about the same control behaving differently on the same vehicle.

If you tap the gas on your Honda civic, you don’t expect it to go flying like a formula 1 car. If you hit the brakes on a Toyota Camry, you know it’ll take a certain distance to stop. If your Honda suddenly flew forward when you tapped the gas, or accelerated like an 18 wheeler when you floored it, that’s something that can cause an accident because the vehicle doesn’t behave predictably.

The steering wheel being able to turn the car 180 degrees with a quarter turn of the wheel one minute, and then take a full rotation to do the same thing the next minute, won’t allow drivers to build good muscle memory for how the car handles. When you have a second or less to react to something like a potential collision, muscle memory matters.
