Tesla does not use any ultrasonic sensors or radar. All the latest models, including this one, rely solely on vision-based data. also Tesla vehicles are still in level 2-3 autonomy. not level 5.
Level 5 vehicles do not require human attention. Level 5 cars won't even have steering wheels or acceleration/braking pedals. They will be free from geofencing, able to go anywhere and do anything that an experienced human driver can do
