"People name boats - why not name your bus?"

Well, for one, the registration of the boat requires a name, (at least
in Mexico), and with the US Coast Guard too, if you register an EPIRB
(Emergency Position Indicating Radio Beacon), or a Ham, or single-
sideband radio on your boat, the insurance company wants a name, the
Port Captains of most ports in the world want a name to call the
vessel by. Most vessels are involved with radio nets, and answer and
call each other by name in addition to call sign. The vessel not only
needs to have a name painted on her, but also a hailing port if she
travels in international waters. The list goes on.

None of these requirements, or customs, if you will, apply to motor
vehicles.
That's why not.
