How to make Python friends with Selenium HtmlUnitDriver?

Question

Python

Google suggested that HtmlUnitDriver is faster than ChromeDriver. Even faster than PhantomJS
Started trying.
First, I launched the Java server itself:
java -jar selenium-server-standalone-2.53.0.jar
Well, the code itself:

from selenium import webdriver
b = webdriver.Remote(desired_capabilities=webdriver.DesiredCapabilities.HTMLUNITWITHJS)

or:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
b = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities=DesiredCapabilities.HTMLUNITWITHJS)

Doesn't work
Even when running java server in warning console:

What did I miss?

I think I've decided. It turns out that you need to add the HtmlUnitDriver itself to the Java server
