How about calling it the “Traction Control Lever”
Back in the ‘50’s my Dad showed me how to pull out of a snow bank or iced up road shoulder using the “emergency brake lever. The trick was to engage it just enough to apply a load on the drive line while going very easy on the gas pedal.. This SOMETIMES stopped the one wheel from spinning and transferred power to the other wheel.
Exactly what present day computer controlled traction control does.
