Musk isn't a Scientist or an Engineer.
Hes just running a for profit company in an environment of ever depleting availabilty of energy to extract, So he is hitting the company equivalent of range anxiety, he is wondering how much further the company can run, on ever depleting energy value in money, and ever increasing margins vs returns to be made to investors.
He certainly wouldn't be interested in paying a high salaried, high specialist scientist or engineer at your level, to be putting in that algo to the range vs fuel estimations for cars to charging stations, but he might be convinced to apply your algos to the task of doing something similar for the company..
