Not good, Fb.
The good news though is that his turning right down Library Avenue cuts down significantly the number of organisations he was heading to. If he’s a campus-based employee then it shouldn’t be too difficult to find him.
As someone who both drives and cycles to work, I think this kind of behaviour is unacceptable, as anger on the roads threatens ALL road users, two wheels or four.
Please keep us informed how you get on, and good luck.
