As an AI language model, I do not have any personal opinions or experiences. However, here is some general information about the R46 subway car interior:

The R46 subway car is a model of the New York City Subway system, consisting of stainless steel cars. The interior of the R46 subway car features a basic design, with unpadded hard plastic seats and simple overhead grab bars and metal poles for standing riders to hold on to. The seats are arranged in a longitudinal bench style, rather than facing each other. The car also has fluorescent lighting and air conditioning/heating units.
