Bottom Line; Humans are dumb.
Easily distracted and unquestionably selfish in motivation, most completely lack the focus and fixity of attention, let alone the physical co-ordination and foresight, to safely and confidently navigate the roadways. This should be no great secret to anyone here. (and it's not just a locally limited phenomenon!)
We stand on yet another threshold of technological innovation that promises to liberate us from ourselves. Society demands safety and security. We wrap ourselves in the "illusion of control", and act agasp with shock and horror when it all goes wrong. Accidents are deplorable and often avoidable. Human error is almost always at fault. Yet we accept this capacity for horrendous mistake as a tradeoff of 'freedom'. But it's a completely false freedom we have received in exchange.
We're promised cars that go fast, yet you can not exceed stupidly low limits because of the propensity for human error. We're shown advertisements that glorify the 'open road', yet millions own and operate vehicles that exclusively end up, day after day, in bumper-to-bumper traffic, burning up time, money, and various limited resources. Communication has expanded exponentially, yet we do not trust ourselves to even touch another device, so easily distracted are we.
Witness the motorcade laws, the enforcement resources, and revenue generation, all built up around this "illusion of control".
There has to be a better way.
And it's coming.
I'm sure we're all aware of the concept of autonomous vehicles. The Google-car, the DARPA challenges, and various other pilot projects are all striving to achieve a driverless car, and it's getting close. It's very telling that the google car has only 1 accident in over 300,000 miles - and that 1 accident occurred when a silly human decided to disable the 'auto-pilot' and take manual control of the vehicle.
California has already approved legislation that governs autonomous vehicles on their roadways. Numerous automobile manufacturers are developing systems that not only self-park, but self-navigate. Of course no technology is perfect, initially. But it evolves, and will get better. So It's coming. It's inevitable. You can be sure of that much.
The only question is WHEN, and are you WILLING?
Are you willing to give up 'control' of your vehicle?
Even if it may eventually mean the end of street-motorcycling as we know it now?
Or will you 'resist' this 'change'?
