Releasing driving assistance features as a &#x27;<i>beta</i>&#x27;? What on earth does that mean here? Are the features ready to use or not? Do Tesla warrant that they work and are safe?<p>Maybe they expect drivers to treat it like beta software - &quot;Please don&#x27;t use these features in production cars. Make sure you keep backups of all drivers and passengers in case of bugs.&quot;
