You could probably connect the vast majority of the city. Every main neighborhood.

Of course if you invested it in aerial gondolas, you could do even MORE . . . but I digress.
To be fair, there is some low-hanging fruit where busways and bus lanes definitely make sense. Oakland is one, thanks to all the excess street capacity in the Fifth/Forbes corridor, and extending the Easy Busway to Monroeville is another (there is a handy rail ROW it could share).
But at some point you will run into similar problems with topography, such that you would need to add expensive tunnels/bridges, at which point the costs will get closer to rail. Of course where Busways have a head start, such as in the case of the West Busway (which really needs a new bridge over the Mon to be finished), you will still come in cheaper than rail. But if you get into completely new lines, the cost savings for comparable service really aren't all that high--after all, the steel rails themselves are not all that expensive.
Of course there is a WAY cheaper alternative to tunnels and bridges, namely aerial cables . . . but there I go again.
