Final week, Elon Musk introduced that Tesla is about to make a significant leap in self-driving efficiency.
He posted that Tesla’s subsequent Full Self-Driving (FSD) replace might be constructed on a mannequin with ten instances extra parameters than the present model.
In different phrases, Tesla’s latest FSD mannequin is predicted to have 10X extra connections in its digital mind. The replace may also embody a significant improve to video compression.
These enhancements ought to quickly allow Tesla autos to “see” and “perceive” the highway in a lot higher element, doubtlessly making them smarter, sooner and safer at making split-second selections.
And that ought to assist enhance Tesla’s robotaxi ambitions.
If inside testing goes properly, this improve might hit the streets by late September.
However there’s an issue.
Tesla’s push into autonomous robotaxis is dealing with authorized scrutiny on a number of fronts. On the similar time, its rivals Waymo and Uber are making progress of their very own.
All three of those corporations are chasing the identical market, however every firm is specializing in a distinct a part of the system that makes robotaxis work.
Which ones is presently within the driver’s seat?
Who Controls the Robotaxi Stack?
As Elon Musk’s current $16.5 deal confirmed, Tesla needs management over its whole provide chain.
And that’s additionally true of its robotaxi ambitions.
Musk isn’t simply attempting to construct the automobile and the software program that drives it. He’s additionally aiming to manage the whole robotaxi service from begin to end.
In tech, a “stack” is the set of layers that make a system work. Within the case of robotaxis, it covers all the things from the ride-hailing app to the {hardware} contained in the automobile.
On the high layer, you’ve gotten the consumer interface. That’s the ride-hailing app or service.
Under that’s the platform layer. It decides how rides are dispatched and priced.
Subsequent comes the AI mannequin layer. That is the mind that truly drives the automobile.
And on the backside is the {hardware}. That’s the automobile itself, geared up with sensors, cameras and computing energy.
Tesla is constructing the whole stack. It controls the automobile and the AI mannequin, and there’s even a devoted part within the Tesla app for its robotaxi service.
This enables Tesla to handle all the things from reserving the trip to processing the cost to proudly owning the shopper relationship.
However Waymo and Uber are targeted on totally different layers of the stack.
Waymo, which is owned by Alphabet (Nasdaq: GOOGL), is all in regards to the AI mannequin layer.
In late 2024, it raised $5.6 billion to increase its Waymo One service and energy what it calls the “Waymo Driver.”
In different phrases, its autos’ brains.
Waymo’s absolutely driverless automobiles already function in Los Angeles, Phoenix, San Francisco and Austin. Testing can be underway in New York Metropolis.
However Waymo doesn’t construct its personal automobiles. As an alternative, it companions with automakers. Magna (NYSE: MGA) helps it scale the fleet, and Toyota (NYSE: TM) plans to combine Waymo’s tech into future fashions.
Uber (NYSE: UBER) is taking a very totally different method, though it’s nonetheless spending closely to remain related.
The corporate just lately invested $300 million in auto producer Lucid (Nasdaq: LCID) and dedicated a whole bunch of tens of millions extra to Nuro, an organization that builds self-driving techniques.
Collectively, they plan to deploy over 20,000 robotaxis by 2030, all out there completely via Uber’s app.
In Europe, Uber is partnering with Momenta to launch robotaxis by 2026.
However Uber is principally targeted on the highest two layers of the stack — the entrance finish of the robotaxi expertise. That’s why riders in cities like Austin and Atlanta can e book a Waymo instantly via the Uber app.
For now, Uber appears joyful to be the intermediary and take its reduce of each trip.
And there’s an enormous marketplace for it to take a reduce from.
Some analysts predict the worldwide robotaxi market might develop from $1.7 billion in 2023 to greater than $400 billion by 2033. That’s a 75% annual progress charge.

However three issues have to occur earlier than we get there.
The AI needs to be adequate to drive with no human.
The automobiles additionally need to be low cost sufficient to scale.
And the foundations need to be clear sufficient for cities to say sure.
Waymo already has the strongest foothold.
Its autos have pushed greater than 50 million autonomous miles and now full over 250,000 paid rides each week.
Waymo is shifting slowly, however Alphabet can fund the rollout for so long as wanted.
And this cautious method has labored thus far. Waymo has a powerful security report, with pedestrian damage crashes far decrease than these involving human drivers.
Uber doesn’t have to fret about its personal fleet rollout but, however the firm is aware of tips on how to navigate regulation. It already works carefully with cities and governments.
And it’s betting that after the tech matures, it may be the platform that ties all the things collectively.
However Uber nonetheless is dependent upon others to produce its {hardware}.
Musk’s plan is totally different. He needs Tesla to scale rapidly.
Tesla’s automobiles don’t use LiDAR or high-definition maps. That retains prices down and permits software program updates to be pushed to tens of millions of autos without delay.
However this technique carries danger.
Tesla faces lawsuits from shareholders who say it exaggerated the security and readiness of its FSD system.
The federal authorities can be investigating crashes linked to its software program.
So public belief stays a hurdle, and these authorized battles might sluggish Tesla’s means to launch its robotaxi program in additional cities.
However does this imply Musk’s robotaxi ambitions might be caught in impartial?
Right here’s My Take
I imagine the winner of the robotaxi race gained’t be determined by who has the neatest AI or the very best wanting app.
It is going to be the corporate that scales a protected and reasonably priced fleet in essentially the most cities the quickest.
Which suggests Tesla’s all-in method offers it a shot at pulling forward.
However until Musk can win over regulators and the general public, Waymo’s regular rollout may find yourself crossing the end line first.
In the meantime, Uber might be joyful to attach riders to whichever fleet dominates…
And gather a toll on each trip.
At this level within the robotaxi race, that may matter greater than proudly owning the automobile itself.
