My territorial parish has three churches. They are half a mile (900m), half a mile (900m), and ¾ of a mile (1.3km) from my home respectively. Despite the proximity, I normally drive because I bring a lot of things with me to each church (I have responsibilities and duties in each). The drive takes 5-7 minutes (lots of traffic lights).
My secondary parish also has three churches. They are six miles (9.7km), eight miles (13.1km) and 8½ miles (13.8km) away. I have to drive there because public transportation takes too long, I don’t own a bicycle, and obviously it would be impractical to walk. The trip takes roughly 15-20 minutes.
My EF parish has four churches, but I only go to one. That one is 3¼ miles (5.3km) from home. Depending upon how much of a hurry I’m in and how long I plan to be there, I either drive or take public transport; the former takes 7-10 minutes (but costs a fortune in parking), the latter 15-20 minutes (but is much cheaper).
