DoorDash is suing New York City over a new law that requires delivery companies to share customer data with restaurants. The lawsuit, filed Wednesday, is the latest in a string of legal tussles between the delivery companies and local governments, reflecting unease over the phenomenal growth of delivery and its impact on restaurants. Last week, DoorDash, Grubhub and Uber Eats sued New York over a separate bill that caps the fees delivery companies can charge to restaurants.
