Let them eat tarmac

I've linked to this because you can read some of the negative comments of car drivers as they find their roads pushed aside to make way for cycle lanes. 

It's a problem, how do you make space for a separate transportation network in a city? You can push the car's aside but as anyone who has cycled in a cycle lane full of parked cars knows, car's can push back. The alternatives are go down ( underground the most expensive way of doing things ), don't built ( cycle on the road and hope for the best)  or go up.

Up is the space monorails, but you need minimalism, tight turning, circles and tiny stations. Things you can't do with traditional heavy rail even traditional monorails. PRT can do it, but I think bikes are the most elegant way of doing it.
