Imagine having to plan a trip to a local charging station every day or two and wait 40 mins to charge your car.
Where people live in apartments (usually in cities), there frequently are too few parking spots anyway, so a lot of people use public transit. Those people at my office who commute in by car do so because they live in villages where public transit connections are too seldom to be reliable. Those who live in the city commute by tram.
Work parking lot charging is also an amenity with increasing prevalence and it certainly is possible that a person that owns a car primarily for a work commute will have plenty of opportunities to charge their car in the 40+ hours a week their car is supposed to be sitting in a work parking lot.
