We discussed this a couple pages back but the nature of my job has me often either driving random places, or staying late to go to meetings/networking events (beer drinking really) with clients and co-workers.
I could always Uber myself around but it's just not as reliable as having my own vehicle parked at work and wouldn't really save me much money. There are weeks here and there where I don't do anything but drive in and leave at consistent times but then I'll have a week like this week where I went to 2 client sites, and a training out in Bellevue and would have been annoyed if I didn't drive my own car to work.
I work with a few public transit users who stay flexible and are willing to do random things but most of them just don't do anything but come into work and leave. They complain when they are expected to drive somewhere during the day, sometimes just outright saying no or re-scheduling until the next day, and rarely if ever stay after to go to the social events and miss out on some of the relationship building that really helps you as a consultant.
