Obviously there is a huge amount of money and effort being spent on automated driving. But I cannot help thinking that this perception technology will prove very useful for robotics in general, factory, home, in space, etc. Car dynamics are fast enough to be useful across a huge number of domains.
In some sense, the visionaries in this space are not thinking big enough. I want visions of mobility with a totally different size, look, speed, etc. autonomous Golf carts? tuktuks? A moving autonomous bicycle carrier? etc
Like imagine a low speed, electric, autonomous, golf-cart-only lane at every train station, for the last mile.
The lead that Waymo has acquired in perceiving its driverless car's environment will be almost impossible to kill. In about 5 years, it'll be like NVidia and CUDA. Tesla's choice to abandon lidar will be one of the biggest oof in business history.
From an execution standpoint you can't work on experimental mobility due to path dependence. How are they going to convince municipal governments to open golf cart lanes? That would require solving two problems (autonomy and overcoming path dependence), and solving just one is hard enough. Once they saturate the market as it is with autonomous driving, then everything will change and opportunities to experiment will open up.
Neal Stephenson wrote a short essay on path dependence that I really like-- https://slate.com/technology/2011/02/space-stasis-what-the-s....
Plenty of people have voiced much larger visions, for decades. There was a spate of futurists in the 80s, Waymo itself, and others like Dave Ferguson of Nuro. But autonomous vehicles have been an incredibly volatile industry. Anyone shooting for the moon (that's not seemingly immune to market pressures) has had those grand visions beaten down by the whiplash of funding. Companies have responded by focusing on those those first, real steps to demonstrate the "easy" stuff. The experimental stuff will come later when they're looking for ways to expand and investor money is more confident in the technology's future.
Tesla never had lidar so they didn't abandon it.
Also, Tesla started FSD in 2016. The very core of their strategy was (and is) to sell $40k car with hardware capable of running FSD.
Cameras are super cheap, FSD chip is reasonably inexpensive. Lidar is not. Maybe today the cost isn't completely prohibitive (I think it still is, because you need multiple lidars) but it certainly was for the first 8 years of FSD program.
Tesla just didn't have the luxury of adding $50k to the cost of the car for the hardware, the way Waymo did. And they didn't have sugar daddy (Google) willing to burn several billions a year for many years.
So the Waymo approach was not an option for Tesla.
And given that in Austin they just reached parity with Waymo (i.e. completely unsupervised robotaxi service), they are not doing badly.

There is no unsupervised robotaxi service in Austin and there won't be, for years, if ever. Just like the way "FSD" is not fully self driving and likely never will be.
According to https://robotaxitracker.com/ there are 7 unsupervised robotaxi in Austin right now.
Are these the cars where the safety driver is in a car tailing the robotaxi, or do they actually run without the need for a safety driver?
https://electrek.co/2026/01/22/tesla-didnt-remove-the-robota...
It seems they run without a safety driver or follow car (mostly?).
However the area it operates is extremely small, and they are still only allowing Tesla bros to try it.
> And they didn't have sugar daddy (Google) willing to burn several billions a year for many years.
Tesla's market cap is $1.3 trillion. Granted the company itself doesn't have access to all of that, but surely if they wanted to spend, say, $10 billion per year on something big like FSD, they could have.
> didn't have the luxury of adding $50k to the cost of the car for the hardware
A little more extreme, but: Tesla has sold something like 8.5 million cars total. If they simply dumped an extra $50K of material into every single one of those cars without raising the price a dime, that would be only $425 billion. That's a ridiculous sum of money, but still <checks notes> substantially less than $1.3 trillion.
I'm not a fan of Tesla's approach to self driving, but

That is an apples to dishwasher comparison. Money is fungible only when it's the same kind of money on both sides. You can't compare market cap like that. (Even for a company whose market cap is seemingly divorced from reality like Tesla's)
You can’t trade market cap for goods and services. Tesla is not exactly rolling in cash these days.
If they had done so, their financials wouldn’t have attracted investors and they wouldn’t be worth near 1.3T
Tesla has the dumbest (and many of the richest) shareholders in recent history. They absolutely would have funded it. Tesla could probably do an offering tomorrow to raise $100B and the share price would be back to ~$420 in a month.

Nobody is talking about any of this using past tense. It is 2026 now, not 2016.

Google Fiber was struggling for a while because cable companies are in bed with power companies and wouldn't let them run fiber through their easement areas. In fact, even cities couldn't run their own fiber.
What you envision might happen in 2100+
Google was struggling because it has the attention span of a crackle addled flea. Including leaving roads in ruins because of “shallow trenching”

the biggest buyer of robotics is the military and i really hope waymo stays out of that
Have you seen the Zoox vehicles? They're what you want.
Still too big tho maybe. What about a Segway-sized vehicle, or even smaller.
It's tough in the US because the one thing we have already going for us is a massive and comprehensive road network. Waymo et al are leaning heavily into the existing infrastructure, which is the right move given the inability of the US to execute major changes to infrastructure these days. Compare that to China, where infrastructure is being actively upgraded to accommodate autonomous vehicles. As nice as the Chinese approach sounds, it's probably a lot less exportable than the 'take the roads as they are' approach of Waymo.

Why? They have started unsupervised taxi rides in Austin. One of their goals was affordability, and their cars are massively more affordable.
You might want to look up the price of lidar in 2026 before talking about affordability.
Every car is more affordable when you don't have to pay a human being to operate it. The difference in labor costs dwarfs the difference in vehicle costs.
Most cars don't have a paid driver. Uber, taxis, and trucking is a tiny minority of drivers.
