Finally, here it is: Laboratory proof that people can't drive.
Japanese scientists recently tried to replicate "shock-wave" traffic jams in a laboratory setting and succeeded.
These types of traffic jams are the ones that seem to occur for no apparent reason. You'll be driving along, minding your own business, and all of a sudden there's massive gridlock. And by the time you get up to where you think there should be an accident or a gigantic sinkhole in the road, there is nothing at all.
Watch the video to see it happen before your eyes. This must be what the helicopter traffic people feel like!
