It becomes a real pain in the neck with the above, to have it installed on the starter, with having to open and close the hood each time you use the switch. Ok! some will say you should check the oil anyway. I haven't yet done it myself, but I have seen others where the switch is installed in the front seat riser below the drivers legs, and another neat installation where the switch was installed in the front cross member. It does require some ingenuity to fashion a on-off leaver that lays flat under the front carpet, again under the drivers feet. This way the switch is hidden from all.
Also in my opinion, having the switch in a location where the driver has quick access in an emergency, might prevent a possible serious situation developing, such as a electrical fire, or even a stuck starter switch.
