So P85D coming next week... and I'm sure not far behind will be the winter nightmare. All the Tesla-branded floormats look to be pretty weak, when pitted against gallons of melting snow, rock salt, and lord knows what stuck in it... compared to something like the WeatherTech mats. The "all weather" official mats look like they wouldn't hold the melted snow off of a set of ladies stiletto heels before it ran into the carpet. So for the northerners out there... what do you use to keep the interior carpet safe from the horrors of winter? Is there something better than WeatherTech?
