This is going to come across as a defeatist post, and perhaps it is. With the ever increasing sophistication of tech, only a fool would think local councils and government won't consider ways in which to utilise it. They might sell the introduction of such tech as being for the greater good of the community and society, others might look on it as ever increasing monitoring of society and our freedoms. And anywhere between. Depends on the views of the individual.
I'm of the opinion, whether we like it or not, that drivers will be ever more closely monitored as the tech (both within and external to) vehicles matures. The drive, pardon the pun, to 'encourage' drivers out of their vehicles and onto public transport (or bikes) will also continue. Again, you can look on this as a good or bad thing depending on your views.
No doubt I also have a line that I wouldn't be comfortable being crossed (in terms of monitoring our movements and activity) however this particular tech and proposed use doesn't bother me. In the past, have I sometimes used my mobile in stationary traffic? Yes. Something I'm not necessarily proud of. However, when I'm behind the wheel, I've never used a mobile when I'm driving. I'm not saying that as a boast, simply a fact. I get that, in some cases, there might be a genuinely urgent need for folk to use their mobiles when driving (and moving), however people should plan ahead and have a hands free solution rigged up if they think they might need to drive and use the phone.
I also think, when it comes to driving in general, we spoil it for ourselves. We all see it, folk regularly breaking the speed limit in town and on motorways (and by more than a few mph.) Tailgating, darting about with no time taken at junctions, roundabouts etc. And in the context of this thread, folk using mobiles when driving. We see all of this going on, many of us aren't immune from doing it. So the assertion can be made 'as drivers, you're reaping what you sowed.'
