: several interesting affects of charged tachyons.
The problem is that those "interesting effects" do indeed violate the
relativity principle. Specifically,the notion of emitting cherenkov
radiation and speeding up does, because whether a given change in velocity
is speeding up or slowing down is fundamentally ambiguous unless there is
a preferred frame. For the same reason that an effect that might cause
an stl particle to shed energy and slow down requires a preferred frame.
