Height restrictions was something I was hinting at, but not really something I expect to see soon. Upon further thought, I was thinking something more along the lines of a “avoid non-truck roads” option in the same vein as the existing “avoid toll rolls” and “avoid major highways” options. Those would basically do the trick and avoid any kind of dedicated truck mode.
Like I said though. Truckers, myself included, would pay good money to have the accuracy Waze provides combined with various trucking related features and real time traffic updates. Especially us short haulers.
