"No regular place of work. If you have no regular place of work but ordinarily work in the metropolitan area where you live, you can deduct daily transportation costs between home and a temporary work site outside that metropolitan area. Generally, a metropolitan area includes the area within the city limits and the suburbs that are considered part of that metropolitan area. You cannot deduct daily transportation costs between your home and temporary work sites within your metropolitan area. These are nondeductible commuting expenses."
@Jeff B. - That excerpt is directly from IRS Pub 463. Again, like all of us CPAs on these threads typically say, it all depends on the particular facts in your situation. With that being said, if you don't have a "Home Office" or a defined primary place of business, you are just commuting when driving around.

"Office in the home. If you have an office in your home that qualifies as a principal place of business, you can deduct your daily transportation costs between your home and another work location in the same trade or business. (See Publication 587, Business Use of Your Home, for information on determining if your home office qualifies as a principal place of business.)"
Which supports what @Natalie Kolodij and @Daniel Hyman are bringing up.
AND if you really want to nerd out tonight, here's a direct link to the aforementioned IRS Pub 463. It's a nice light refresher read for me after answering a few ACA tax questions this afternoon. https://www.irs.gov/publications/p463/ch04.html
