I used to do a little mental exercise of speed vs distance, time involved in practicality, time plays a big part of the equation depending o what amount of time you can reasonably expend to make the rounds so to speak, time increases as radius increases vs speed of vehicle.I usually start at 100 meters as a practical walking distance, a few kilometers on bike after about 5 klicks I look for a motor vehicle because of the time factor.If I lived in the "low countries you can bet bike would be my preferred mode of travel( especially since I no longer have to punch the clock) It always seemed to me that Europeans have a great sense of practicality. A ICE vehicle is an expensive master.
