ARK models are using robotaxi at $2.50/mile
My best guess would be $2.50 per mile initially, dropping 10 cents per mile every 2-3 months reaching around $1 per mile after 3 years.
Then a much slower drop to 40-50 cents per mile over say 5 years.
Factoring in cleaning, tires, insurance, app support, admin etc, 40-50 cents may be a floor.
The other reason 40-50 cents may be a floor is, at that price, people care more about the quality of the service than they do a lower price.
Sure they might be budget operators who eek out a living on razor thin margins, but the trade off may be some inconvenience, cars not well cleaned, longer waits, older cars.. buggy app..
No one has ever said Robo-taxis will be the solution for 100% of the population, but they have the potential to accelerate the retirement of older ICE vehicles... sometimes no car is better than a cheap old car.
Many 2 car families will become single cars families, Robo-taxis eventually reducing new car sales by around 50% is my guess.
But longer term there will be a generational change, teenagers can start using Robo-taxis from age 12-14 with perfect safety,,and parents will be glad children aged 16-25 are catching a Robo-taxi home after a night out.
Why does that young city dwelling person who used Rob-taxis ages 14-25 and can get one in 10-15 minutes every time they need one, need to bother with private car ownership and getting a licence. Sure some will get a licence but many will not bother.
Some people without a licence will still want to own a cars or perhaps even multiple cars.. but many will not.
It is far easier to give up something you have never had...
IMO Telsa a pursuing Robo-taxis mainly because of the mission and to benefit humanity more generally, it will be profitable and a steady source of recession proof income, but it will not necessarily dwarf all other income streams... Sure it will do billions of miles per year, but the bigger question is the margin on those billions of miles. The value of a largely recession proof income steam can not be overstated.
In a recession giving up private car ownership for a Robo-taxi, is a move many would make.. especially if they have just lost their job.
