Wonder why more vehicles are not set up with dual ignition systems similar to what is done in aviation.

On a good day, a Rotax 503 Dual carb, Dual ignition 2 stroke ultralight trike I used to fly could get 1300 FPM climb. (solo) But it was a bit of a dog if I disabled one of the ignition systems. I did that as a partial experiment to see and know how it would behave if there was an in flight failure of one of them. I was an ultralight instructor for a while and wanted to know everything about what limits my trike might present in flight. Nobody but me on board when I did that and it was only on the ground testing. Well, limited to short hops down the runway anyway.

I do suppose a dual coil & plug/single trigger set up could be done that would give the extra spark, but somehow I'm not sure if that would be beneficial or not. The head would need to be different or modified and not sure how the more intricate workings of flame propagation might affect performance or engine longevity for example. Hmmmm? maybe that's why a potentially complicated thing is not done for simple machines like scooters... and lawn mowers maybe. Guess I partially answered my own question... but still I wonder.
