How did Waymo do this? As far as I know, replacing drivers with an AI was the goal of ever-money-losing Uber and Lyft, however, Waymo managed to get to this much sooner while having less funds.
Google hired a bunch of people who'd done well in the 2005 DARPA Grand Challenge [1] - including Sebastian Thrun and Chris Urmson who lead the winning team.
Thrun is also behind Google Street View which in some regards [2] looks a lot like a self-driving-car sensor suite. So Google was having LIDAR-equipped, high-precision-GPS-equipped cars drive every street in every prosperous country, starting back in 2007. Uber wasn't even founded until 2009.
Other Google hires had a similar background - such as Anthony Levandowski who competed in the DARPA Grand Challenge with an autonomous motorcycle. He later gained fame after being caught stealing a bunch of LIDAR schematics and similar trade secrets while leaving Google for Uber.
We also know from court documents that Google was throwing around mountains of cash, even when the self-driving-car division had no revenue. Waymo was set up as an "internal startup" giving employees "equity" so Levandowski left not just with internal documents but also with over $100 million.
That's a stark contrast to a lot of other players who'd need to show investors a lot more to get a lot less. This endless money was undoubtedly helpful in giving them the confidence to design for L5 autonomy from the start, no need to design a lesser system to get the money coming in early. And of course if you can pay $100 million for one guy, you're not going to baulk at the cost of a few $10k LIDARs so long as the people making them claim the price will fall to $200 for automotive quantities.
The 2005 Grand Challenge simplified the driving problem a great deal - no pedestrians or moving vehicles to deal with, safe and driveable route guaranteed to exist - but it did a lot to focus development efforts.

L4. Waymo can't "drive everywhere in all conditions" [1]. (Nobody can. Not to L4 standards of never requiring "you to take over driving.")
Whereas Waymo's taxis don't have anyone in the driving seat at all?
That's L2.
Do you mean this in the sense "even humans can't do this, it's too strict a requirement" or in the sense "no self-driving car has achieved this yet"?
Waymo existed for like a decade on the basis of "we have a pile of money and our founders think it's cool". They moved slow and broke nothing. They made slow, incremental progress exploring the self driving space for years with plenty of funding and no expectation of a product launch.
So when a bunch of other companies came along, years and years later, and were all "we're going to have self driving cars next year!!!", and Waymo had their "oh shit, we better actually make this into a product or why do we even exist " moment, they were already in a really good place. They weren't rushed, they probably could have pivoted to a product a year or three earlier. They'd already solved the problems everyone else was just handwaving.
If it was accidental, they sure got lucky in the amount of time they were given with relatively little pressure, and in the timing of that competitive pressure at the end.
Waymo (January 2009) is older than Uber (March 2009) and has always been part of Google/Alphabet. So to answer your question they did it with enormous amounts of time, money, and talent.
* Time - Waymo started work on this in 2009 and are now getting a faster adoption in 2024. Uber started in 2015 and sold it off by 2020. Time has given Waymo the advantage of slowly ramping up and starting with toe-dips.
* Funding - Waymo has spent more money to get where they are now (probably 2-3x what Uber spent in total). Google also has deeper pockets than Uber, which means that there is less pressure on quickly ramping up Go To Market or immediately getting profitability.
* Culture - Waymo was much more cautious (likely because of funding structure) which is now paying dividends in terms of regulatory approval and consumer trust ('sometimes you have to go slow to go fast').
With Cruise gone now there's basically just Waymo, Zoox, and Tesla (bit controversial) that are the names thrown around when talking about self driving market share, and out of those only Waymo has a functional service.
Waymo's safety data, on carefully curated paths, with human assistance and in the most car-centric cities in the world, is worthless. When these things hit the real world, with black ice, open manhole covers potholes etc. etc. don't expect lidar to save you from disaster. Maybe the average safety case can be made, but that won't be acceptable if they regularly kill people by confusing cows with flying plastic bags.
