If all cars were autonomous
My immediate thought is a dystopian version of this article:<p><i>If all cars were autonomous, society, the economy and the environment would all suffer. Here is how…</i><p>* You will be forced to watch non-stop ads in these automotive cars, similar to how some taxi services work today.  You can turn these off for a fee of course.<p>* Hackers or bugs in softawe may easily cause global traffic jams<p>* Congress will pass laws controlling when, where and how you may travel<p>* You may be blacklisted from traveling in any autonomous by corporations, governments, police etc.<p>* The aggregate amount of automotive travel will increase exponentially, causing more carbon emissions and even worse traffic since more people will have access to travel<p>* Sprawl will get worse, as people move further away from urban areas since they can do other activities in cars.<p>* Investment in mass transit will diminish, since funds will move towards automatic cars.
