### Feature and motivation

This has always been the default behavior for Ruby.

I think a lot of people are annoyed with how much extra stuff gets sent to the console (especially Firefox — https://github.com/mozilla/geckodriver/issues/619).

Once we document how to turn on logging for the drivers (I'm working on it), I think we should swallow the driver output by default and (maybe) direct people to the docs for how to turn it on/save it.

### Usage example
