The plus side is that, if we keep to our proposed schedule of each
giving the other a ride to work twice a week, my gas consumption will be
reduced about 40%. The minus side is that that means I will refuel less
frequently and thus have less data to post.
So far, the carpooling isn't that hard. I wake up about 10 minutes
earlier in order to get to the meeting point (about 1.2 miles from my
house) on time, and other than that, commute times are so far about the
same. Only less stress on the days I don't drive.
Another downside is I am not able to listen to my books on the CDs as
much so far. Perhaps that will change in the future. But I think the
notable and dramatic dip in my gas usage makes up for it.
