But now, Volvo owners, at least, can rest assured that their packages will be waiting for them inside their cars when the workday is over. New digital key technology enables people with Volvos to choose their vehicles as a delivery and pickup option, a Volvo press release asserts. The car owner can track when the car is opened and then locked. Volvo says that of the 100 people who tested out the tech in their pilot program, 86 percent agreed that the roam delivery system saved them time. The technology also makes it possible to remotely heat or cool the car and check how much gas is in the tank through your phone, the press release says.
