Not at all for work. Earlier when I lived in a bigger city I was usually assigned to places where it would be inconvenient to use public transport (not always though and then I would use public transport). Now I moved to a small city and live a two minute walk from work.
And there are times I need the car. But if I go visit a bigger city and have no rush and it is free I would most likely see more of the city. I wouldn't so much replace driving a car with public transport - I would just do more traveling daily.
