> its first international service could be Waymo's biggest challenge yet

Waymo have been testing/operating in Tokyo for about half a year now, so this would actually be their second international territory.

Wayve (1) are driving similar test vehicles in London

Apparently they're not affiliated with Waymo, rather they are a competitor (2)

I wonder how much engineering was needed to adapt to driving on the left side of the road.

I imagine that for some things you just flip a switch, but for anything neural there could be learned associations where certain objects or events are more common on certain sides of the road. I guess that Tesla would he more effected by that given their end-to-end neural architecture.

As a human driver I've never had much problem with the left right thing but a lot of road rules and conventions are different. That's always been trickier going from the UK to Paris or the US.

Maybe you can get lucky by mirroring the situation left-to-right. Certainly the hardest part of driving on the left isn’t being on the “wrong” side of the road but being on the “wrong” side of the car.
