One of the famous youtuber in the Tesla community, TeslaRaj, risked his own Tesla Model 3 to demonstrate how well the Tesmanian Tesla Model 3 floor mats are. He managed to pour 5 gallons of water into the Tesla Model 3 rear trunk mat. In addition, he pours another 2.5 gallons of water into the passenger side mat. For his courage, this 10 minutes video is worth watching! Thumbs Up to TeslaRaj.
