FLAT ROCK, Mich. — Executives with the North American arm of engineering company Robert Bosch showed off an electric-hydraulic steering system for Class 8 trucks that they said will aid in the transition to autonomous commercial vehicles and announced a “breakthrough” in substantially reducing emissions of nitrogen oxide from diesel.

SCHAUMBURG, Ill. — The good news is that heavy truck brake technology is moving forward at a dizzying pace — a clear boon for highway safety. Unfortunately, there is a troubling knowledge gap among a large segment of the technicians responsible for keeping up with those brake maintenance advances — even a lack of basic brake maintenance.

Consumer trust in self-driving cars has plummeted after high-profile roadway fatalities, with almost three-quarters of Americans now saying they are too afraid to ride in an autonomous vehicle, according to a new survey.
