How would you go about designing such a system? How would you handle those situations where bicycles and cars will have to mix? As there will be times when either the roads for cars or the roads for bikes will have to cross each other or do you purpose some sort of tunnel/bridge system for that? But even with that there will still be points where the two have to mix such as at entrances to malls and shopping centers, etc.
