Tesla Model Y Pure Vision Safety Features Put Through The Paces Jun 09, 2021 at 8:41am ET ++ How well do forward collision warning and automatic emergency braking work in a Tesla with no radar? Tesla owner Kevin Smith recently started using his YouTube channel for the purpose of testing his Model Y, which has no radar and is using "pure vision" for its Autopilot system and advanced driver-assist features. Smith is a Manufacturing Software Engineer who took delivery of a Tesla Model 3 in 2018, and paid for the Full Self-Driving package. Sadly, he never got to use the feature in its full capacity.
