Rain was pouring and wiper was on as I pulled up to speak at the drive thru to order. As soon as I cracked my window to order and the wiper began to wipe from bottom of windshield, all the water wiped came into the car. Since it was raining hard, a $*it load of water came in and soaked the interior. Lesson learned, avoid opening window for even a crack when raining hard and wiper on. For those who are concerned about blind spots when merging into lanes, keep your rear view camera on at all times. Unfortunately, the rain can obscure the lens. Whilst driving, if you need to perform a change on the screen, if the buttons are close to the left or bottom edge, use your thumb to stabilize your hand before pressing buttons. Likewise, if the buttons are near the right of the screen, use fingers 2-5 to grab the back, then use thumb to press buttons, can do also with buttons on screen bottom. This will help reduce the time you take your eyes off the road to position your fingers to select the correct button to press.
