Park-and-ride is totally a thing. People in the burbs should (and in some places, do) drive to rail stations outside the city and park in lots there. This is not "last mile", though, ideally you drive a relatively short distance to a rail station. Most of the trip should be via train. This reduces congestion in the city and accommodates suburban-types.
