BBC had a driver disguised to be invisible (seems he dressed to look like the seat) and filmed people's reactions: Video: watch people lose their minds over a Tesla prank Humorous reactions from drivers passing the car.
I'm very glad he didn't manage to create an accident. The other driver's reactions are funny but they are seriously distracted.
There's a different quality to people's reactions than to this guys earlier invisible driver videos. The early ones the reaction was like it was impossible or supernatural. In the current one people's reactions seem informed by expecting that driverless cars are possible and coming. More OMG there's one of those things.
Great reactions from everyone not seeing a driver...in a couple of year people will be surprised to see a driver when autonomous cars become a norm.
