Zoox run their tests in San Francisco, a city known for chaotic traffic conditions. They do so rather successfully (see their YouTube videos). This accomplishment alone means they are not really "far behind".
Well I wouldn't expect them to post Car Crash Compilations of their own making.
San Francisco is one of the oldest cities in California, as such, the city layout is largely from the pre-automobile days.
A look at google maps shows the city is splits in large perfect squares of roads themselves split in smaller squares. It's typical US modern layout, the antithesis of European layout.

So they're not starting from zero + a speculative acquihire if that makes sense, at least in my opinion

Zoox is in prime position to be a better nuro
Amazon's market cap is currently $1.2 trillion. If they spent $2.5B to acquire zoox, that is only 0.2% of market cap. Not a bad risk/reward ratio.
Hard to tell since you haven’t defined any particular reward. Keep in mind the risk/reward ratio for a particular investment would be the same regardless of the percentage it made up of the larger portfolio.
As a side note, risk/reward ratio is the same, but when making bets with positive expected return, you must consider bankroll size and risk of ruin. The VCs are realizing they can’t play a $300M/year game where the probability of winning is 20%, even though the expected return is 100x.
The behemoth company with custom mapping of every road in your country and manual remapping of construction sites will provide a far better experience than the scrappy AI start-up. (And they can probably leverage that to gain better insurance rates, or to get driving licences in places where second movers can't.)
* Assuming any player finds a viable business model, and that our current understanding of ML, Computer Vision, and control systems is sufficient to produce a commercially viable product.
That's enough to justify the purchase.
Why do you say that?
