Tesla is adding radar and I predict before long it will add LiDAR because that's the only way to get to Level 3, which is a requirement for moving forward in California
They're not reading the actual FCC document then, which says:
Strategy: The move brings Tesla's sensor approach closer to competitors like Ford, GM, and Rivian, who utilize multi-modal systems (cameras plus radar) for their driver-assistance features.
Potential: This 'HD radar' could provide critical redundancy and data needed for achieving higher levels of driving automation and improving system performance in all conditions.
