To record a drive, you just launch the app. After a splash screen of the comma logo, the app automatically goes into logging mode. If you mount it on a dashboard and start driving, it starts logging. If you stop&nbsp;driving, it stops logging. The only instructions from George&nbsp;are to &#8220;capture such that you would feel comfortable driving the car from the footage.&#8221; I didn&#8217;t even see a menu for settings, though it&#8217;s possible to enable&nbsp;cellular video uploads via a setting on the comma.ai forum, as accounts are managed&nbsp;by phpBB. I suppose the way to log out is to clear app data.<\/p>\n\n\n\n<p>Here&#8217;s the logging interface:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/chffr-logging-1-1024x576.png\" alt=\"Camera on.

The forum has a leaderboard where users can see who has earned the most comma points. After a couple of hours of driving, I earned&nbsp;1012 points, though there are a lot of bonus points at the beginning.<\/p>\n\n\n\n<p>You can view&nbsp;your own data via the&nbsp;driving explorer feature of the website, which shows what the camera captured, your location, your speed, and the time. You can&#8217;t play back the drive&nbsp;in realtime, but you can scrub through it by dragging the slider.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"678\" src=\"https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1-1024x678.png\" alt=\"driving explorer screenshot\" class=\"wp-image-2697\" style=\"width:690px;height:auto\" srcset=\"https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1-1024x678.png 1024w, https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1-300x199.png 300w, https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1-768x509.png 768w, https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1-1536x1018.png 1536w, https:\/\/wysz.com\/wyszdom\/wp-content\/uploads\/2016\/07\/driving-explorer-1.png 1944w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>It was pretty rough on my battery, and I prefer to have a navigation app in the foreground when driving, so&nbsp;I&#8217;ll pause testing for now.
