One mile takes maybe 20 minutes to walk? Call it 30. And I'm going to deal with a big, expensive device to trim that down to 15? I'm not going to take a car for that distance either unless there isn't decent walking infrastructure. And, if there isn't, I'm not going to take a Segway either.
Well good on you that you have all that extra time that halving the commute time isn't worth it. Is this the only trip that day? What if there are many?
