Six weeks ago some guy texted Elon Musk that it would be great if the dash cam could autosave whenever the horn was used.  The feature was just introduced as part of a software upgrade.  It's impossible to imagine Volkswagen or any other legacy automaker doing something similar.  Sure, Elon is a tool and the Tesla fans are almost as obnoxious as the detractors, but it is impressive what he's accomplished.
