Traffic light vigilante

If I weren't doing this med student business, I'd be a traffic light vigilante. I'd spend my days flying around the city with a video camera and a stop watch to expose the stupid traffic light sequences that plague this isolated capital of mine. And then I'd do a PhD where I would devise a formula that would calculate ideal traffic light sequences that optimise traffic flow and minimise driver frustration. And then I'd campaign to have my perfect formula applied throughout the land. And if people failed to recognise my genius, I'd find out how they program the lights and in the wee hours of the morning I'd set about the light sequences.

And then do you know what? The world would be just a little bit of a better place.
