People will operate businesses that own their own cabs or individuals their own personal vehicles. Just as we do now.

And the infrastructure we have now will continue to operate.

How will such an infrastructure be built and be operated. Its a mystery. But its already been done by private enterprise.

As to why only one slow lane could be used, I don't see why that would be. Perhaps you could explain. We have many lanes operating now and robotic vehicles would simply use the same lanes.

Perhaps PRT has these limitations. Robotic vehicles that operate like the vehicles that operate like the vehicles we already have wouldn't.

Of course, we do not yet have robotic vehicles that can be trusted to operate in rain or other extreme conditions and that can discern their environment well enough to be safe.

But once we, there's no reason to follow the PRT pattern. We'll simply follow the patterns we already have. Only with much more sharing (cabs) and much more efficiency.
