This new service won’t use those trucks, at least not at the beginning. Instead it will function much like Uber’s existing platform: Some people will sign up to drive items across the country, and others will join so they can send packages without having to sign a contract with established shipping companies. The service will likely bring “surge pricing” to trucking, too.
