Since 2016, General Motors has fought orders to replace allegedly defective Takata airbags in over six million of its pickup trucks and SUVs, arguing in a series of petitions that the recall is unnecessary because the airbags are safe. Four years after receiving the first of the petitions, the National Highway Traffic Safety Administration (NHTSA) has yet to rule on them, leaving owners of the vehicles in limbo.

U.S. transportation officials are seeking to ease deployment of driverless cars by amending certain safety standards, drawing strong protest from groups who say the move is premature because the safety of  self-driving technology is unproven.

America’s workforce is aging. According to AARP, nearly half of new jobs in the U.S. last year were filled by workers 55 years or older. Due largely to ongoing labor shortages, this disproportionately small demographic accounted for more than 1.4 million of the 2.9 million new jobs in 2018, many of them in the fast-growing sector of warehousing and distribution centers.
