Car service Uber has added a new feature to its family-focused plan that could make rides with your children a bit easier: kid-friendly tablets. The company recently announced that Nabi 2 tablets have been put into hundreds of cars in its fleet in the Washington D.C. area. This initiative is part of Uber Family service, which already gives parents the option to request a vehicle with a car seat, and they are looking to offer this option in other markets as well.
