Pure ice is nasty - I remember one time when I was still in MN we got ice during the day, and my driveway was glazed when I got home. About 50 feet long and with a little over a 2 foot rise, I had a hell of a hard time making it all the way up, even with my 4x4 Bronco. (Which had positrac differentials front and rear.)
A colleague had video he took from his apartment balcony of the hilly parking lot where a guy came out, went to his vehicle (walking on the grass because the pavement was too slippery), got in, pulled out of his parking space - and immediately went into an uncontrolled slide until he crashed into a retaining wall.
This was bad enough, but THREE MORE PEOPLE came out over the next 10 minutes and did EXACTLY the same thing - with nearly the same results; the only difference was they crashed not into the retaining wall, but into the vehicle(s) already there.
I am SO hurting today... That surfing next to it took a toll... And looking back, I was on the downhill side of it... If I had lost my grip, I probably would have gone under it. Or if it had slid into the Fungus, I would have had a good chance of being smashed by the door...
Be glad you're hurting - it means you're alive. Could have been much, MUCH worse.
