In Kerrytown, this seems to be a more common occurrence than should be normal. While walking towards Zingerman's, I spotted a car going east on Catherine just before the Fifth Street traffic light. From that direction, cars can only go south on Fifth - not straight, and not left. But the car first tried to go through the traffic light, then tried to go north on Fifth, and finally figured a way to get back the right way. But not until a few cars had to be careful not to get into an accident.
I lay most of the blame on this at the feet of traffic engineers, because we have a fairly counterintuitive system of one-way streets in parts of A2. Unlike NYC, for example, where almost all of the streets alternate one-way. we have some parts of town that are just one-way, some that are mostly two-way, and some where the streets change, or point in opposite directions (e.g., Madison at Packard). Drivers have a great deal of responsibility to not only read the signs but look at how traffic ahead of them is flowing. But the city could have tried harder to have some consistency in its traffic pattern design.
