To help commuters survive the London Underground strikes relatively stress-free, ride-hailing app Uber has positioned itself to get people where they need to go by suggesting they use its ride-sharing service to reduce wait times. To aid those stranded by the industrial action which commenced 18:30 on Wednesday, running until 21:30 tonight, Uber is using heat maps showing ride demands made through the app during last year’s strikes, to estimate where the highest volume of travel requests will come from.
