OE-LBA-nice idea. We feel vulnerable because of the much larger SUVs and Hummers on both sides of my Toyota sedan (woops- I did not mean to boast), while they talking on a handy/cell, but are too arrogant to use their turn signals.....
However, that would require a very heavy-handed government. Our ancestors (Vorfahren?) wanted a fairly weak central govt. and free enterprise. I guess it is like many complaints about 'zoning' in Bozeman, Montana. Many people around there resent almost any form of government, but look at what can happen with fairly uncontrolled housing development.
