In an eye-catching video, Ford and Agility Robotics recently touted their partnership and vision for autonomous delivery, illustrating the need for a system that can navigate from a parked vehicle up a set of stairs to reach the front door, for example.

The big picture: Autonomous vehicles are expected to decrease delivery costs by eventually removing drivers from the equation entirely, but the logistics of last meter delivery in particular remain intractable.

Details: Industry leaders in the autonomous delivery space are generally pursuing two solutions to get deliveries into the hands of recipients: parcel lockers and “motherships."

The parcel locker model involves storage units in highly trafficked areas that separate and secure packages for numerous recipients. Amazon already has lockers at Whole Foods locations.

  • Parcel lockers decrease delivery costs, mainly by reducing driving distances.
  • However, if parcel lockers proliferate, they will likely demand some infrastructure investment in city centers, where real estate costs are high.
  • Not to mention, parcel lockers put a burden on consumers to ‘commute’ to retrieve parcels and to get them home.

In the mothership model, a large autonomous vehicle would not only hold the parcels, but also fleet of drones or bots that can navigate stairs and apartment buildings for example.

  • This model has a high potential for cost reduction as no human driver is needed in the vehicle.
  • However use of drones at scale will require a federal regulatory framework, and the drones themselves will need HD maps for every potential delivery location.
  • This model could run into additional complications in dense cities as buildings and high foot traffic could make navigation more challenging.

The bottom line: The last meter of package delivery may prove to be the biggest challenge.

Ben Sasse emerges as GOP Trump critic ahead of November

Sen. Ben Sasse (R-Neb.) has dialed up his spicy slams of President Trump, including this swipe at yesterday's signing ceremony: "The pen-and-phone theory of executive lawmaking is unconstitutional slop."

Why it matters: Trump increasingly looks — to business and to fellow Republicans — like a loser in November. So they're more likely to create distance to save their own skins. Sasse also won his May primary, further freeing him.

Pelosi: "States don't have the money" for Trump's unemployment order

House Speaker Nancy Pelosi claimed on "Fox News Sunday" that states don't have the funds to comply with the executive order President Trump signed on Saturday, which requires them to cover 25% of an additional $400 in weekly unemployment benefits.

Why it matters: Many state and local governments have had their budgets devastated by the economic impacts of the coronavirus, which have caused expenses to soar and revenues to plunge.

Kudlow says he regrets claiming Trump couldn't use executive order for unemployment

White House economic adviser Larry Kudlow said on CNN's "State of the Union" Sunday that he regrets suggesting this week that unemployment benefits can only be extended by Congress.

Why it matters: President Trump's decision to bypass Congress to sign four executive actions, including one that provides $400 per week in extra unemployment benefits, has prompted outcry from Democrats and even some Republicans who believe he is overstepping his constitutional authority.
