I guess the testing at this stage have nothing to do with charging to the Vehicle, rather software tweeks, mesurements to get the right data for EPA, NEDC miles, Autopiloten stuff and most importan driving 1000 of miles to verify everything is OK.
The panel tweeking, testing of the aerodynamic, crash tests, roll over..... Is not done on public roads and ready months ago in closed facilities. (Some of the Beta is proberly crashed and burned months ago, for testing purposes.)
And quite normal to se mules/betas all the way up to delivery, guess they would like to have the software ready when the first cars is delivered, not the same problem as D cars where the torque sleep was not ready and energy consume did not match the Custmers measurements.
Remember Tesla is not as other cars, software is also changed, tuned after delivery.
We also need teesers.
