Whoops, turns out I didn't actually understand what "constant bearing" meant. What I actually meant was "no rudder/steering" which is exactly what people would imagine as travelling in a straight line.
A constant bearing actually gives a Rhumb line: https://en.wikipedia.org/wiki/Rhumb_line
Don't apologize. Your use is perfectly correct, you're obviously not referring to compass bearing.
