“Black Panther” kept the top spot in box office rankings last weekend. According to Box Office Mojo, “Black Panther” did $41.1 million, and:

Disney’s A Wrinkle in Time landed in second with an estimated $33.3 million over its opening weekend. The result is just below the $35 million the studio was expecting and well below Mojo’s aggressive forecast. Reasoning for the film’s lackluster debut will most likely focus on Black Panther’s continued dominance within the marketplace as well as the mixed reviews the film received heading into the weekend.

OPEC may be affected by U.S. oil exports. According to Bloomberg:

Oil risks sliding back under $60 a barrel as a surge in U.S. shipments to Asia threatens to undermine a deal between OPEC and its allies, according to ING Groep NV.

The resulting fallout could drag down crude prices after a rally of more than 40 percent since June, he said.

The Whole Foods division of Amazon.com Inc. (NASDAQ: AMZN) faces trouble with vendors. According to CNBC:

Tensions between Whole Foods Market and some of the most important brands it sells in its stores will come to a head on March 19, when they will congregate for a recently announced summit, sources familiar with the situation tell CNBC.

The grocer notified certain vendors about the meeting by email last Saturday. It is set to reassure the brands of relations after Whole Foods’ sale to Amazon. It comes after a rocky few months for the grocer, which has been trying to shift from a local orientation to a national one, without sacrificing the selection and relations that set it apart from larger peers like Kroger and Albertsons.

Self-driving trucks have become a reality. According to CNNMoney:

A startup has upped the ante in the race to develop self-driving vehicles. Two days after Uber announced self-driving truck operations in Arizona, which feature a backup driver as a precaution, Starsky Robotics said it has completed a seven-mile drive without a human in the vehicle.

In mid-February, Starsky conducted the test on a closed portion of Route 833 in Hendry County, Florida, with no traffic.
