Does the average person spend 140 mins commuting each day?
If they were not driving in mind numbingly boring traffic, they might be able to do something useful, like read a book, play a game, or answer emails.
It is likely in a city there there is a mixture of trips at different times for different durations.
Most airports in large cities have flights which leave at all hours of the day.
Many students attend university at odd hours, including night lectures, people work night shifts
The capital cost of the Robotaxi is probably around $25,000 and it should be able to do 1 million miles.
So the capital cost of the Robotaxi is $2.5 cents per mile. Electricity is probably around 8-10 cents per mile. Need to add in cost for tires and cleaning
But a cost basis of 30 cents per mile might be close to the mark,. So if they charge 50 cents per mile. That 24 mile trip costs $12 and the profit is $4.80.
Even if we assume each Robotaxi only makes $10 profit per day, a fleet of 5,000 makes, $50,000 profit per day, or 18 million profit per year from one city.
Yes fleet utilisation probably determines the ROI. Mapping fleet utilisation for a city is a complex task,, it is a mixture of customers moving from public transport, Taxi, Uber, private driving.
But it is more likely that each Robotaxi makes around $30 profit per day... Tesla will eventually have a fleet of at least 1 million Robotaxis, probably more like 20-40 million.
A large fleet size is the best way to recoup the FSD R&D costs.
