Looks like Tesla's navigation system is getting an upgrade. Also note that it seems like Tesla is still interested in eventually doing battery swaps at some point in the future:

Just because they patent something doesn't mean they are going to actually put it into production. For example look at the Tesla patent that shows scavenging battery/drive-unit heat to provide heat to the cabin. They never actually did that. (But a lot of people assume they did because they saw the patent.)
