Oh no, I don't think we are missing the point
You are right, many people will prefer autonomous vehicles (I don't have any problems with them either) but with the politicisation of sustainable development private vehicle ownership will come under increasing pressure .....already city councils around the world are obsessed with 'livable cities' with an emphasis placed on pedestrians, light rail, cycle lanes, etc.
They will gently nudge you out of your car by making it increasingly inconvenient to own one: fewer parking areas, changing central city streets to pedestrian only traffic, surcharges to enter high-density urban areas, high taxation on privately owned vehicles, and eventually some areas may in fact ban human-driven cars altogether.
Basically, they'll annoy you untill you give up your vehicle ......they'll do the same thing for pet ownership no doubt
I'm all for sustainable development, we need to be more responsible with resources and do our best to limit the damage we do to the environment. My problem is with the undemocratic and often dictatorial way sustainability is being forced on all of us. My faith lies with engineers, scientists, and designers ....rather than with politicians, city planners, and beaurocrats.
