You have to be in a very privileged position to receive affordable tickets. I am lucky to work for a huge employer that offers a JobTicket which costs me 69 euros and they also subsidize half of that. Who doesn’t work at a company that has JobTickets can buy the same for 220 euros per month
Stops aren't really a good measure of distances. Three stops by a regular all-shacks city bus? Three stops by rapid transit-type rail? Three stops on a semi-fast regional train? Three stops by long distance-express train? Those different modes of transport all result in massively differing distances as measured in kilometres (and also time).
If there was "free" or "low cost" way to "get into town" perhaps some of those would occur, not replacing a car trip but replacing a delivery.
One thing I heard was though is that most of the additional transit trips were not replacing car trips but were trips that would not otherwise have been taken at all. Which is not a bad thing in itself, but it would have been nice to displace more car usage.
