It's not. Water is much worse under those conditions. Fresh snow has a lot of air mixed in with the flakes and will compress quite a bit - water does not do that at all.
Depends on the amount of snow ....
If your talking the same depth as water then agreed , but if its like a foot of snow , + depends on the snow ..
Compacted , powder or sludge ... And what ever might be in between .
I have driven onto a soft shoulder of a road , and it does the same thing , pulls the car into itself ..
Depending on the speed your driving at , it can be easy to panic , over correct , and lose control .
Same with gravel , gravel over a hard surface can be like driving on ice ..
I have driven on dirt a lot in the past ( Mountains ) ...
Here is a good one ..
I let some one else drive my car since I had been driving a while .
We were on gravel and they were driving a little aggressively , so I told em to slow down before there was an accident ..
Well the driver tells me we are in perfect control and about 5 seconds latter a car comes the other way , also driven aggressively ..
The driver of my car stomps on the breaks and promptly losses control , we slide onto the wrong side of the road ..
Now thankfully the other car driven by an equally skilled and intelligent driver has the same problem - under breaks loosing control and slides onto the wrong side of the road !
Both cars harmlessly pass each other fully out of control ....
After coming to a stop I look at my Brother and ask him if he is prepared to drive a little slower now that he has endangered our lives , lost control of the car , and hopefully realized he is no where near as good a driver as he imagined .
And there in lies the problem I guess , no one dies in " The Need For Speed " or any other car racing game ...
But in the real world , you may only ever get one mistake ..
