I've not noticed anything posted here, but it looks like the
much-delayed Heathrow pods are finally in service (or are they
technically still on trial?). Anyone here tried them yet?

Here's a recent video I came across:

and bumpy ride, but still better than the previous bus, and the views
are good. You even get delays before journeys start, just like the Tube:

I notice they have right-hand running, despite being from a UK company.
This initial system isn't exactly ambitious, with very few stops (I
think two in the car park, and one at the terminal).
