Beyond round and black, the "Circle of Traction"

[55 Rescue Dog]

The "Circle of Traction" concept has been around for a long time for race cars that still applies today on all vehicles, even motorcycles. It has been replaced on most modern cars with computers. ABS brakes, traction control, stability control, torque vectoring, etc. Basically it comes down to if you are using 100% of your available traction for braking or acceleration, there is zero traction left for cornering. The fastest race car drivers are the ones that can smoothly blend the 3 forces together to keep all the available traction within the circle of forces. It applies to everyday driving too, under all weather conditions, especially if you don't have all the electronics to control your car for you.
