I would be transparent about it instead of trying to be sneaky and pull a fast one on customers.If you were Tesla what else would you do? The factory making the projector headlight is probably maxxed out. The other headlights they have plenty of and work as well.
Different ways Tesla could have handled it:
A) let people accept old lights with a credit and take delivery sooner, or wait longer for new lights.
B) ship cars with old lights but offer a free retrofit later when supply is resolved
C) slowed production to match the supply of headlights coming in
D) limit the new lights to Performance or Performance and LR only moving forward, and offer credit for outstanding orders that will be receiving old lights.
What if Apple ran out of A15 chips for the iPhone 13 and started shipping them with the A14 from the iPhone 12 without telling anyone? Most people wouldn’t notice a difference in day to day performance with the old chip. Does that mean that’s OK for them to do? Should people accept that?
