Wife has a 2002 RX300 with AWD and AS tires. During inclement weather when most RWD cars are slipping and sliding all over the road, the RX300 will handle and drive like a dream. Have occasionally taken it out to test the limits of adhesion when the roads were packed with snow and the local authorities are encouraging everyone to stay home. It reinforces my sense of security knowing that I have to push the driving limits fairly hard before reaching the threshold of control. The threshold is so far above normal driving habits that snow pack roads during inclement weather is not even an issue.
Seems to me that I get the best of both worlds driving in snow or hard dry asphalt in 10 degree weather. You guys drive what you want. More power to you. As for me, I'm perfectly content with AWD and UHP AS tires.
