Driverless Tractor Set Loose in Walmart Lot

Mashable points to the latest sure-to-go-viral video: A driverless tractor running loose in a Walmart parking lot, wreaking exactly the type of havoc you’d expect. The video, from a Canadian store, does show how the tractor is eventually stopped. On Mashable, Charlie White has to wonder “why it took so long for someone to consider jumping up on the tractor’s running board, opening its door, and turning off its ignition.” (More viral video stories.)
