I figured that would be the next step, but there's still a lot of inertia: some stations are bookended by perpendicular streets and would require the train to the parked on the road while loading, which may raise legal or political issues.
I hear they're trying to move all the stations to grade separated ones though, which should alleviate that.
Also, you'd have to get the public accustomed to "want to get out here, have to be in these cars", which, knowing the public, will take a big information campaign and still end up with people frantically charging through cars and screaming at conductors to open the doors...
