Video: Now this is the ultimate network reliability test. Vodafone rigged a $300,000-plus BMW M6 race car with three Samsung Galaxy S7 phones, blacked out the windscreen, and set up three Samsung tablets in front of the steering wheel to stream real-time video from the phones' cameras over its 4G network.

Then the team put racing legend and V8 Supercar champion Mark Skaife behind the steering wheel, stuck Vodafone Australia's CEO in the passenger seat, and unleashed the car at full speed around the Calder Park Thunderdome in Victoria.
