I'm confused.....if you didn't order until 6/27 why did you need to confirm the change from radar to vision? From Tesla Support:
"Beginning with deliveries in May 2021, Model 3 and Model Y vehicles built for the North American market will no longer be equipped with radar. Instead, these will be the first Tesla vehicles to rely on camera vision and neural net processing to deliver Autopilot, Full-Self Driving and certain active safety features. Customers who ordered before May 2021 and will receive a car with Tesla Vision will be notified of the change in their Tesla Account prior to delivery."
It doesn't make sense to me that they would make you confirm the change when they haven't offered radar since before May.
