Today everything is about on-demand services. Tesla has many opportunities to radically reposition itself in the transportation/automotive space that would also greatly benefit Tesla customers.
Here are some examples:
1. Range as a Service
With the reintroduction of software limited batteries, it would be interesting to offer 'Range as a Service' for those occasional long trips that that could not justify initial purchase of the full battery range.
2. Enhanced Autopilot as a Service
Again for those occasional long trips or difficult situations that may arise, the ability to engage 'Enhanced Autopilot as a Service' as needed.
3. Full Self Driving as a Service
For those cars with appropriate hardware/computing, enable 'Full Self Driving as a Service'. Reasons mentioned before, but even such as a medical emergency to transport autonomously to care.
In each of these offerings it would simply be an initiation from the console as well as to conclude the service. As with SuperCharging these billings would reflect in your account.
I recognize Tesla is very cash now hungry; but their unique over the air capabilities here offer new, additive revenue streams that should not be ignored from customers who could not afford/justify the upfront or after purchase of these capabilities.
