Indeed. Metro Cammel clearly designed a custom cab for the Metro application where all-round close visibility was considered less of a priority, and incorporating that particularly poky little driving cubicle behind the left-hand window. The standard Stadtbahnwagen Typ B vehicle, capable of street running in Germany, has a centrally located driver seat in a full width dedicated cab and a large flat and deep single-pane windshield. The nose of the standard carbody also differs in having a pronounced taper towards the front and the large cab side windows with very narrow pillars separating them from the windshield result in excellent short-range visibilty.The (current) Metrocar wouldn't be allowed to run in traffic or busy pedestrian areas because of the relatively poor view from the cab in any direction other than forwards. Even with thick pillars between the front windows they didn't meet the railway structural standards, so neither one thing or the other really. The Stadler tram-trains for Cardiff look better in this respect, but the design from the same company for T&W is different with much thicker corner pillars.
For example, here is a 3rd generation example somewhere in the Bochum area.
