Salmon's quote: "Ask any auto engineer - when you are asking a set of wheels to both drive AND steer, your asking a lot."
They been building them like that for 30 years. Plenty of time to get it right. I think it's an awesome thing. If you start to get stuck you steer and give it gas and if you aren't already buried it will climb out.

Most, if not all the front wheel drive cars have traction control too.
It's kind of funny to see an arguement that a rear wheel drive car can compete with a front in a real winter environment. Don't even try it! How about this; You can 'get by' with a rear wheel drive vehical. All wheel drive will do good but those vehicals are very expensive and turning that second drive train kills gas mileage.
