It's easier to manage a vehicle that plows just a little. It's easy to correct for understeer. You do it every day in your cat and on your bike. In other words, you have to go to opposite lock, have to turn the steering wheel or handle bars opposite of the rotation of the vehicle around its axis, have to turn the opposite way from the direction you had been steering. But even oversteer can be a sustainable and more or less stable condition.
Racing drivers can induce oversteer by applying power to their rear wheels.
This is called throttle steer. Adhesion in the service of forward propulsion subtracts from side thrust, so a greater slip angle is required. In a car, you're only occasionally oversteering, and only rarely at truly neutral steer. You're nearly always understeering in a car. That's why you have to keep your steering wheel turned.
