So let me get this straight. You think that the problem is the cyclist and not the fact that drivers get distracted? Hmmm. OK here is something that you might consider. Mirrors. More to the point, mirrors on your drivers door. Use them before opening them. When I overtake a parked car I usually leave 3 ft clearance. This can naff off the car behind me, but tough, for the very reason you mentioned here.
News flash number 2. Cycles are road vehicles. I do not know about the US, but in the UK we have had the designation of carriage since about the 1850s. This is long before some bloke named Benze was messing about in his shed. So cyclists have been road vehicles longer than cars.
News flash number 3. Many major cities are becoming car free zones, especially in the town centre. London has a congestion charge to discourage excessive use of the car and it is attempting to encourage cyclist into the city centers. What you may find is a similar system used in city centres as a way of making the cities work more efficiently. Sure trucks and delivery vehicles will always need access, but you may find a park and ride system, or other investments in public transport. This means that the cycle will become a very viable commuter tool.
Anyway, unless you are proposing an investment scheme in the cycling infrastructure, you are just going to have to learn to use your mirrors.
