Some of what you say is valid. Unfortunately... as I ranted - the few have ruined it for the many.
You did notice that I mentioned a local area, low power cell phone jammer and why they haven't developed on yet? The point is to not infringe on the people in the building on the other side of the wall or the person that need to make an emergency call... its not unreasonable to wall to the door and make that emergency call or better yet; contact the store manager, floor clerk, receptionist or broadcast on the intercom for a doctor. A call from someone who is rational, controlled and hopefully dispassionate - will get emergency help on the way a lot faster, with the right equipment than 10 or 15 excited shoppers all calling 911. Half the stores we go in - most people don't know the address or what floor to direct them to anyway.
80% of the cell phone calls I am forced to listen to in public areas should be "Private", with a capital "P". I have no desire to know who loves who more, what Billy Bob intends to do to Becky Sue - its hard not to stare, which makes everyone within ear shot feel like a Perv, eavesdropping on a conversation that is being forced on us. There is no justification for washing dirty laundry in the public pool, expecting no one to take notice.
Recently I posted that my rust-free, 80's Bronco, which had new running gear, steering box, cooling system, Wheels and tires...all within the last 2 years. Was totaled by a Sweet little thing, cute little 20-something, on her cell phone, ran through a red light - never hit the brakes, at 50+, on a residential street. Lets just replay the woulda, coulda's of someone crossing the street; who wasn't in a 5800lb Bronco (which I mentioned - was totaled! Frame bent, axle broken, passenger side seat moved over to center console). After getting out of the truck, unbelievably ironic - a 30's something lady, pushing a stroller (cute couple of twins (?) were in it); seeing me dazed - she made the call to the police, ambulance and tow trucks. I had my cell, in my pocket, but didn't even remember I had it until I was home safe. Let's just say the situational stress does not allow us to think rationally at times.
So, as much as I hate to be bound by arbitrary rules, laws, regulations - when there is a clear and present danger that people are unconscious about their own safety, and disregard the safety of law abiding people going about their lawful daily business - then it may be time to regulate what common sense seems to have failed to do.
The coffee, conversations, smoking, putting on makeup while driving at 80 mph and even fiddling with the radio; are not a good example of loss of personal freedoms. Loss of concentration maybe; but not a reasonable loss of freedom if you are driving a 2 ton car.
If you are having a conversation that gets you that involved; by the way, thats the most dangerous part of using a cell phone, next is texting, dialing is way down the list; most folks are aware of that danger. What really narrows our focus in a conversation is thinking of the next thing to say. Our higher brain (math, conversations, disruptions) have the ability to overpower things like breathing, heartbeats; something like a deep conversation will easily change our focus. Might be a time to pull over and talk it out? If its just light conversation to relieve the boredom, it might even be a benefit - besides 4-eyes watching the road might even help.
