I agree fully on the dangers of using mobile when driving, however I think that objecting to someone receiving call when a passenger in a vehicle or visiting your home is rather short sighted, not to say draconian. Same applies to when in a restaurant or on the golf course. Its is quite simple to turn a mobile to silent so the user knows someone is trying to contact them.I have never allowed anyone, ever, to have their mobile phones turned on when in one of my vehicles with me whilst the engine is running purely on the grounds of safety!
I also make my objections known if anyone visiting my home receives a mobile phone call, or when eating out when they don't have the good and basic manners to turn the blessed things off.
I know it is hard for some people to believe, but life did go on in times gone by before these damnable devices were invented, which is why I saw to it to ban them from being used at my golf club when out on the course!
I do own a mobile, but normally never have it turned on.
Does it not occur to you that there are many people who depend on mobile phones for important, sometimes life saving communication, for example, those with elderly vulnerable or ill heath parents or other family members, those who are on call as members of the emergency service or medical practitioners, there are many examples and I am reminded of golfer who suffered a heart attack on the course , who would not have survived had his partner not been able to summon assistance by using his mobile. Presumably there is no one who you might want to contact you in an emergency so you might as well bin your mobile if you hate them so much. On the other hand perhaps you do think a mobile might be useful should you need to contact someone should you have an emergency situation which is why you carry one.
There is no problem with mobile phones at all, its just a matter of people using them in a manner that does not disturb others. I would be the first to ask someone not to carry out a loud conversation in a restaurant and I think they should be turned silent in in most public places. Good manners and consideration is eat is needed, that's all.
