California and a group of 16 other states on Tuesday challenged the Trump administration's decision to revise strict U.S. vehicle emissions and fuel efficiency rules put in place under former President Barack Obama.

The U.S. National Highway Traffic Safety Administration (NHTSA) said late on Tuesday it was proposing to cancel a planned hike in higher "gas-guzzler" penalties for automakers whose vehicles fail to meet minimum fuel-economy standards.
The Trump administration might lower fuel economy targets as soon as 2021. Automakers desperately want concessions, spending $49 million on lobbying in 2017.
Low-volume carmakers like DeLorean can't build any cars until the EPA and NHTSA finish some long-overdue rulemaking.
