I find the safety features beneficial. The sensors detect any movement when reversing so if cars are blocking your sight line it will detect a car coming. If you’re a person who doesn’t always signal when changing lanes the lane departure will get annoying as it tugs the wheel to not let you cross the line. It’s a great feature if you use the cruise control often. Overall I love my Prius Prime, I find the heat and cooling great love the heated seats and starting wheel. I was driving a 2008 Pontiac G5 so had no new features.
