I have been going thru the same considerations on my Lotus 7 replica. I ended up selecting the on-off-on toggle switch as used on the bug eye Sprite. I almost selected the early Jag XK style self-cancelling switch. But remembering the how annoying it was to have to turn it back on when it cancelled waiting at a light to turn left made me steer away from that direction (no pun intended).
As always, your choice will be accepted or rejected by a State official that will have a case of "anal-necktitus" and if he/she will listen to your reasoning will depend on if they have installed a glass belly button so they can see what's going on around them.
