The meaning of free public transport

A reader writes in regarding the call for free public transport:

I am so totally in favour of this.

I’m just not sure that the bus drivers will work for free, the diesel companies will provide free diesel, the road user charges will be free.

Of course, if we mean “every other taxpayer should pay for some select people who have access to public transport and ability to use public transport to get a further discount beyond the massive subsidy they already get”, then that’s quite a different discussion.  I’m not sure I’m in favour of that.

Exactly.
