Volvo's implementation isn't really about consumers, and we'd look at someone strangely if they flat out refused to pick up a key when offered. Instead, the firm is exploring how people will interact with their cars in the future and how car usage will change. For instance, self-driving cars won't sit in the car park while you're in the office, they'll ferry other people around during the day. Similarly, being able to share keys digitally makes it easier for car clubs and ride-sharing firms to manage their fleets. So, yeah, relax, Volvo's got an eye on how the future of transportation will shake out, you probably won't have to deal with it for a while.
