Hyundai's self-driving fuel cell cars complete a record highway trip

Future self-driving cars don't have to be pure electric vehicles, and Hyundai is determined to prove it. The automaker just had a five-strong fleet of Level 4 autonomous hydrogen fuel cars drive themselves 118 miles from Seoul to the Winter Olympics' home venue of Pyeongchang. That's the longest any self-driving vehicle has traveled at highway speeds (around 62-68MPH), the company claimed. Previously, they had to putt around at slower speeds, and frequently on limited road sections. Three of the cars were shiny new Nexo SUVs (such as the one above), while the other two were more familiar Genesis G80 sedans.
