They're nice assistants and reduce my commute fatigue considerably, but yes, when I use my Jeep's adaptive cruise control system I constantly have to be on the lookout for stopped traffic too far ahead for the system to properly recognize or things entering my lane from the side. My understanding is that this is common on all of the radar+camera systems, Tesla's included. Life would have been a little better for them had they not bundled relatively common ACC tech with bleeding edge lane-management tech, called it all one thing (autopilot) and then said that thing was in beta. Basically they hyped almost-industry-standard ACC off the charts and are now getting special scrutiny for it. On another note, saying your driver safety system is in beta testing is its own fail, just with the word "beta" that screams "still has bugs." They really need to watch out with the crossing over of tech culture idioms to vehicles. There were probably other ways to position that tech.
