MSN.com started a poll with this title earlier today. I'm not going to start a poll here because I'm sure what the overwhelming favorite vote would be. Anyway, here's the current results with 31,062 votes cast so far:
15% Cars that drive themselves
27% Hydrogen-powered cars
4% Web-connected cars
11% Flying cars
23% None of the above; give me more muscle cars!
20% Something else
As you can see, our mindset isn't too far away from leading this poll.
