At those speeds, you wouldn't even really have time to panic.
No control of the car, except perhaps rear braking and foot off the gas.
I guess I would have enough time to throw in a few expletives
, but not enough time for the fear to sink in.
By the time the reality bites, I guess you would be stationary.
I think the same would be true for any car/bike crash.
Having crashed both car and bike through loss of control, you just react instintivley and then it is all over.
My first crash was a car in snow. I had recently read in a book that I should dip the clutch. Trust me, if you start to slide in the snow, do not dip your clutch.
My second was on a motorbike at naughty speeds, and my tail pack (bag that is attached to the rear seat) slipped into the back wheel, locking it up. Having spoken to others this is common, moral of the tale, don't get a tail pack. When the back wheel locks up all you can do is keep turning into the skid, which fish tails, and hope it does not high side you before you stop. I got high sided and the bike landed on me before we went our seperate ways. It did not hurt until I tried to stand up.
I guess the point I am trying to make is that you will tend to react based on your training, or lack of it, and you don't have a lot of time to think or be scared. Until about 10 seconds after it is all over.
And so in answer to the original question. I would take foot of the gas and maybe use the brakes. No point in steering. Although I am sure that if I was approaching a wall, I would turn the steering wheel anyhow.
