lift-off oversteer

If it's an emergency, ie can not safely make it through the turn regardless of skill level, defintely going to hit something in the road, stopped traffic, an accident, straighten the car and full brake. Yes, you may go off the road but you won't slam in to other people/vehicles.
Not sure of any track books for cars, but reading " A Twist of the Throttle" really gave me a good understanding of the physics of speed and some of the two wheel techniques transfer. Like looking through the corner.

I don't see how VSA can help you with lift-off oversteer. It can only cut power to one or both rear wheels, right? How could it help in a situation like this?

As far as I know, VSA is just a traction device that's active mostly on acceleration. I don't think it's like the corvette system which applies braking to specific points to reduce oversteer or understeer...and I don't think it's like an active yaw control. I think it's just to prevent wheel spin and on throttle oversteer.
quoted from wiki,
"Snap oversteer is the propensity of a vehicle to spin dramatically during a turn (usually unexpectedly). This is most common with mid-mounted engine, rear wheel drive (MR) vehicles. Mid-mounted engine vehicles have a much lower rotational inertia than a vehicles with a front mounted or rear mounted engine. The lower rotational inertia of mid-mounted engine vehicles causes the vehicle to spin much faster than a front or rear mounted engine vehicle. Snap oversteer if unexpected can catch the driver off guard when cornering, ultimately leading to loss of control of the vehicle.
Snap oversteer is induced when the throttle is lifted while mid-way through a corner, often by inexperienced drivers trying to reduce speed after braking too little. With mid-engine vehicles the rule for cornering is "slow in, fast out", rather than "fast in, slow out" for front-engine vehicles. Mid-engine cars are setup with more understeer to prevent entering corners with too much speed."

this car isn't overly twitchy under reasonable speeds, you can brake and lift as needed wihtout too much worry. Say you take a 40 mph corner at 60 mph you can still have a margin of safety, however if you hit it at 90 mph that is where things get twitchy and you can get into trouble. The car feels safe at most reasonable speeds, if you get over your head then you can pay a price if you don't know exactly what to do.

Some may think that taking a curve marked as a 20 mph curve at 30 is reasonable. Some might think taking the same curve at 45 is reasonable. 45 mph may be too hard to lift mid corner, 30 may not be hard enough to cause problems.
I guarantee that your mother, wife or girlfriends don't feel that your driving is as reasonable and controlled as you do.
