This is Awesome ! Really nice creative project ~! Some things you can do to improve this further.

Maybe try changing the orientation of the letters so they can be viewed by the driver behind you as well ?

Try to add a 3d printed mini shower head, and most importantly, implement a code which can synchronize the spray intervals with the SPEED of the car (would also help if you use more sprayers with nozzles for more precision )?

How about using a "marking paint" instead of water (some paints can be rinsed away though)?

That's cooler than I expected, and a much better truck trend than "Rolling Coal".
...assuming it's only used with "printer ink" that will disappear after a couple rainstorms.

This is a nice variation of Chalkbot. It used chalk based paint to write messages during the 2009 Tour DeFrance.

The "printer ink" in this case is rather cheap too as it is water
