VW fixed the problem of dirty backup cameras with this simple technology

For the past week, I've been testing out a VW Beetle "Dune," a special edition of the iconic reboot of the legendary "people's car."

The car is loads of fun, has an amazing audio system, and is pretty cheap, at less than $25,000.

But it also has a nifty feature that no driver is ever going to see - although he or she might hear it, and it solves a problem that every driver with a backup camera has faced when the weather gets rough.

Check it out.
