There is a Tesla software defect. 1. I stepped into my Tesla Model Y. There was no vehicle in front of my driveway. A delivery van came to park in front of my driveway temporarily. It is a traffic violation according to the California Vehicle Code Section 22500(e). 2. I put my foot on the brake and put my car in the reverse gear. 3. Then I made an adjustment on the CONTROL screen. 4. I put my foot on the accelerator to continue to back up my car. The screen doesn't show the rear view anymore. This is a Tesla software defect that the screen should display the rear view as soon as I push the accelerator in this case.
