Learned something new today, accidentally. Was driving in stop and go traffic when I noticed my seatbelt was locked (wouldn't release in and out). I decided I'd unlatch the seatbelt, let it back in to free it up, then relatch. To my surprise the car freaked out, disabled auto steer and said something about reducing speed. I couldnt read the message as I was busy stomping in the accelerator to prevent my car from near stopping (getting rear ended because the car would like to save me by slamming on the breaks didn't sound like fun). Just sharing my observation as it was unexpected, unnecessary, and dangerous. Hopefully that seatbelt sensor doesn't ever fail.
