I could not get up my driveway today. We had snow last night and as
soon as the wheel spins there is the power shuts down. This is not the
way you need to drive in lousy weather. We also have a Lexus and have
to turn off the computer so that we can get up the driveway.
Is the a way to shut down the Prius computer? This is almost a
necessity in sometimes in winter driving.

In some situations it works, in others it doesn't. I've experienced
precisely what you describe but for some reason it crawls right up my
driveway, and I can't do that in my Explorer without selecting 4WD. A few
years back I had a Mercury Villager that couldn't even dream of climbing my
driveway in winter. I wonder if it makes any difference how much pressure
one applies to the accelerator pedal? I use a light pedal going up my
driveway because I had the pedal to metal when I failed to climb my
neighbor's driveway. In fact, I found myself at a standstill, ICE at an
idle, and pedal on the floor.

You can do it, very slowly. Try 1 MPH. We all have an unconscious fear
of stalling the engine, but that does not happen with a Prius. There is
no way of shutting off that function; it is needed to prevent damage to
one of the electric motors from too-high RPMs. Your non-hybrid Lexus
has a different drive system.

I think that Toyota has a design fault here. There isn't any reason
why you can't spin the wheels to get up the driveway. I disagree with
the assessment that the car will be damaged by turning off the
anti-skid function. I think that it is more realistic to think that
the engineer who developed the car has never experienced this problem.
This is far from a perfect car in bad weather. I am now thinking that
it is only a warm weather car that needs a lot more design work. I
wish that there was a way to contact a Toyota person who really
understands the car. The dealers are not that well versed on how the
car is expected to perform.

In my experience, spinning the wheels makes it worse, perhaps because it
heats the tires, maybe because it turns compacted snow into ice. I crawled
up my driveway (compacted snow) a litter while ago while paying attention to
the traction control light. I went up at a slow, steady pace and saw the
light flash 5 or 6 times. Trust me when I say I couldn't have done this in
my Mercury Villager and I certainly can't do it in my Explorer without
engaging the 4WD. Of course, you may have a steeper incline that is
impossible to climb without 4WD, I don't know. Once the compacted snow has
been turned into ice by spinning one's wheels or act of God, all is lost
without a shovelful of sand or kitty litter. :-)
