Prius allergic to snow and ice?

You all seem to be from the US on this group. Sorry to interfere, I am
European! Nobody is perfect </;o)=

My son has a 2004 Prius with which, this winter, he had a surprising problem
worth mentioning: that car, full of automated controls is allergic to snowy,
icy, muddy and slippy roads in general.

When the grip on one front wheel is poor, the power on that wheel decreases.
Then instead of having a 2 wheel drive, you get only one... and with all the
power on that one, the risks of having a poor grip on that one is enormous.
Then, quickly, the car refuses to move! And you become a star on that nice
little road moving up to ski resorts... This could also happen on wet gras,
on mud etc.

According to the instruction manual and to the dealer, there is no way to
"cancel" that anti-slip safety. Is not it a pity?

Any one of you has got that problem? Any solution?

I have a previous generation, but I've heard of the problem you describe.
Our 2002 works just fine - we push the pedal down a bit and the car goes
slowly, but I guess the 2004s and later stop trying when the wheels slip.
IIRC pushing the accelerator all the way down will make it keep trying. And
it is true it can't be cancelled - it is to protect the hybrid system.

You ignores, that with a conventional car you are able to use the
coupler carefully. But the Prius with its electro engine with 400 nm
torque from 0 rpm has no chance to reduce skating on slippery ground
without assistance of the computer.
I hope, I will not be surprised, when I will climb up the hill from
Grenoble (where I am living) to Chamrousse (where I am skiing) this winter.

Fiat lux!

Yet my husband drove his car on a particularly cold day, when many of the
roads here in MA were coated in black ice. While all the other regular cars
were slipping and sliding all over the place he was able to travel at a
reasonable speed, maneuver ably, and had nary a problem up hills or winding
roads in his 2004 Prius.
