Longer post tomorrow to commemorate Prince Harry visiting and to give a little illustrated history of the University campus.
However, very briefly, have made more progress on robot taxis. Still don't know really where the term comes from, but it turns out there are two types: those that go along the same route as taxis (which are only called 'bus-type taxis' by me) and those which serve remote areas where taxis and buses don't. This seems to me to be a bit of a conundrum: not licensed must surely mean that any insurance policy won't be valid in the case of accident, but these unlicensed drivers are providing an essential service. Will have to think about this....
