Everyone complains about Boston drivers and rightly so (really, though, there are mobile buffoons in every city). One of the common complaints is that Boston drivers don't use their directional.
But what's really annoying are the drivers who do use their directional — when making a turn onto a one-way street.
We know you're turning right. You have no other option.
But it happens all the time. You're behind someone turning onto a one-way street and their directional is on. The irony is that these are the same idiots who don't use their directional when it matters.
