Getting back to the San Francisco Bay Area, I've been seeing these "ZIMonitor" cargo containers on the highway for the first time in past coupe weeks now. After a quick Google search I learned that these are special temperature controlled cargo containers that customers can monitor adjust remotely. How cool is that!? Learn more about ZIMonitor and The Z Factor which is another top of the line ZIM cargo container model rolled out for 2021 that can also be seen on Bay Area highways in recent weeks . . .

All that new ZIM transportation tech aside, you can still find plenty of the more older model containers on Bay Area roads.
