I'm also finding this really sad. Its painfully obvious to anyone who has used either system recently the majority of commenters have no idea what they are talking about either, the amount of nonsense in this thread about both Tesla and Mercedes ADAS implementations. As always with car discussions on this site, people's feelings about brands and their stereotypical owners seem to cloud any reasonable discourse (especially when Tesla or FSD gets mentioned, sigh). That and of course everyone on Hackernews is apparently an automotive industry expert to boot...
