[Christ]

I'm not saying it couldn't be done, I'm just saying that it's not a "tomorrow" sort of thing.

In other words, you're not going to see Caterpillar or Detroit or White putting cans of salt water on their trucks come next week, or even next year, ya know?

I can imagine there being a salt water filling station at truck stops, though.

Probably not of much concern, but would this cause more rain? Imagine the millions of miles each year that people drive, and all the water vapor that would get released over land (including what already gets released)... would that affect weather patterns?
