U.S. new energy truck maker Nikola (NASDAQ:NKLA) said today that it will provide autonomous driving assistance systems for electric heavy-duty trucks starting by the end of next year. The system, called PlusDrive, is similar to the hands-free highway driving system offered by automakers such as Tesla, GM and Ford, but a human driver must be present and focused on the road. The system handles most highway driving tasks and assists human drivers in non-highway situations, including reversing to the unloading dock.
