One Step Closer to Flying Cars

So this link popped up last night in my feed reader, discussing how yet another legal hurdle has been passed to getting us our flying cars.  (OK - roadable aircraft, but still, it's progress)

Here's my thing though the more I think on it, the more mass aviation transportation is BAD.  Here's why:

I drive through one of the worst traffic snarls every day.  Not the worst, but it's nasty.  And yes, taking some of these vehicles off the road would be a good thing for traffic there's some basic aspects to consider:

1 - People will still think of them like cars and thus navigate like cars
2 - People don't pay attention to what they're doing in their "car"
3 - An accident like the one in Cincinnati can kill at most one or two dozen people.  A flying car that suddenly fails due to mechanical issues can take out not only its occupants but anything it hits - with a lot more force than just the speed it was moving.

Yes we will see more regulation with something like this.  And yes we will see a lot of licensing and laws.  But once you're in the sky things get a lot more hairy.
