I took a London black cab recently for a trip to the hospital, and the driver at one point overtook about 200 metres of stationary traffic, going around several "keep left" bollards, to go through the red light that the rest of the traffic was queuing for. The driver was in his 70s, so I'm not sure if he's just been doing it so long that he doesn't care about the rules any more, or if he was struggling with some kind of age-related brain degenaration.

In his defence, I did get to the hospital well in advance of my appointment. It reminded me of the old Sega game Crazy Taxi.

IIRC, it is almost impossible to give a taxi cab driver a ticket in London.

Nah - easy to give them a ticket, and they'll be severely punished by one (insurance).

However, most ticket issuing in London is by automated cameras, and Taxi drivers know where all the cameras are.

I recently took a Waymo test ride (round trip, two separate segments) in Los Angeles.

It was extremely uneventful - in a good way - while navigating urban traffic, road construction, unprotected left turns, etc., and felt (subjectivity alert!) a lot safer than many of the rideshare drivers I've ridden with over the past 8 years in LA.

I would definitely do it again and would feel safe putting a family member in one.
