Skills, or lack thereof

One of the curious skills that I've never learned to acquire is how to enter a car without getting either myself, or my car interior, wet when it is raining outside. Certainly, I can open the back door and drop my stuff inside without getting it wet, but for me to get into the car without either my umbrella getting my car interior all wet, or me getting into the car wet... I think it's a skill beyond my means. If anyone has any suggestions or lesson plans, I'd greatly appreciate it.
