Thing is you don't see many commercial vehicles (eg delivery/repair vans) being involved in crashes on urban or suburban streets because they either have a class B license or are carefully screened. This is not to say it never happens of course, but in my experience commercial drivers are alert because driving is key to their ability to make a living, and patient because they want to get to their next job safely. They generally mindful of rules of the road and give way at pedestrian crossing or wherever. On freeways, most semi-truck drivers are similarly responsible.

The drivers who make me nervous tend to be in SUVs or lifted pickups/crossovers, followed by sports cars. IME people who pick a big car to feel safe tend to be poor drivers. I went from liking Volvos to ride in to being scared of them when I got a motorcycle.
