Although I don&#x27;t deny that tanker trucks are pretty amazing feats of engineering, sometimes I just want a glass of water. Instead of figuring out how to purchase one, drive it, and park in my back yard, it&#x27;s pretty nice if I can just turn on a tap, fill a glass, and turn the tap off again. The tanker truck isn&#x27;t &quot;wrong&quot;, but it sure is a lot to deal with.
