Not necessarily. Unless I am misunderstanding what specifically is being referred to as a tram. In Portland, Oregon for example, we have small trains that run at street level and share lanes with automobile traffic.
Those things are already illegal and SOPA doesn't address them anyway. I think the important point is that the internet should not be restricted in an attempt to preempt any criminal activity (because it won't work). Instead, the internet should be left alone, and those who choose to do illegal things on the internet should be prosecuted.
