My initial statement separated the BMW owning class from the “commuting from Worcester because they need to live there” class.
I guess my point is that if you have a super nice car (or even just an average car), and guaranteed parking (either payed or free) you tend towards drive even with traffic and gas. The commuter rail just won’t appeal to you for any number of reasons, but mostly cause it’s so slow, and surprisingly expensive.
Now, if you have access to the red, blue, orange or green lines, that’s a whole different story, because those lines function almost as S bahn type systems, and are exceedingly fast and useful.
The commuter rail has the gargantuan, yet slow feel of an intercity train trip, yet you’re only traveling short distances.
