This week's Question: Automaker Volvo is inviting 300 owners of XC90 SUVs and S90 sedans to try out a new app that connects car owners with convenience services. Through the pilot program, users can receive remote fuel delivery, valet car cleaning, and maintenance from their phones. Authorized providers of the services receive a digital key – a one-time-use location- and time-specific device that allows access to the vehicle. The car can then be returned to its original location or moved to another requested area. What do you think? Will you use "car concierge" services?
