I'm conservative. I think buses should be free. Then they'll actually get used and all the secondary benefits they were supposed to bring will be much more easily realized.

You need public transport in major cities. Not everyone can or should drive.

You need private transportation almost everywhere. Not everyone should be forced to ride public transport just because it exists.

As long as people have an actual choice that's not manipulated in some way then I think the system is fine. It has a public function and it provides immediate and secondary benefits.
