Well...all is not as rosy as Musk paints it..in Tesla land--long article packed with info--I cannot but wonder as to why Tesla owners are not up in arms..or..perhaps this is new info..and the push-back hasn't yet started?

About a decade ago, Tesla rigged the dashboard readouts in its electric cars to provide “rosy” projections of how far owners can drive before needing to recharge, a source told Reuters. The automaker last year became so inundated with driving-range complaints that it created a special team to cancel owners’ service appointments.
Tesla years ago began exaggerating its vehicles’ potential driving distance – by rigging their range-estimating software. The company decided about a decade ago, for marketing purposes, to write algorithms for its range meter that would show drivers “rosy” projections for the distance it could travel on a full battery, according to a person familiar with an early design of the software for its in-dash readouts.
Then, when the battery fell below 50% of its maximum charge, the algorithm would show drivers more realistic projections for their remaining driving range, this person said. To prevent drivers from getting stranded as their predicted range started declining more quickly, Teslas were designed with a “safety buffer,” allowing about 15 miles (24 km) of additional range even after the dash readout showed an empty battery, the source said.
The directive to present the optimistic range estimates came from Tesla Chief Executive Elon Musk, this person said.
