"Alternative Vehicle Lanes" ...?
What do you think that double-white-lined mini-lane is that's next to the flow of traffic? You know, the one right in the path of opening car doors that cops and delivery vehicles park in?
We solved our city transportation problem 130 years ago when we invented the "safety" bicycle. Hooray, no more pooping horses!
Then, we invented our city transportation problem a few years later. Damn, smoking cars and trucks!
Later, we solved our city transportation problem again in a charming, creative way. Hooray, an electric trolley system!
Then, we inexplicably made the SAME DAMN MISTAKE AGAIN, and removed our trolley system in favor of increased car traffic lanes. Hooray for WTF!
So, I think this group is the best one capable of understanding that all of our transportation problems have already been solved. What we haven't solved is the perverse tendency for humans as a group to do monumentally stupid things for short term gain.
Brandon, I don't think you'll have much luck adding valves and a timing chain to an engine that was very precisely designed to not be a four-stroke engine. If you're looking for projects that take the same kind of skill and patience, though, perhaps you could work with meme theory and group psychology to move our society away from carhenge
