When driving down the interstate the carbon fiber roof suddenly delaminated of its top layer causing the cars behind me to have to slam on the brakes as chunks of carbon fiber flew off the car. This is a known issue with the BMW carbon fiber roofs that is worse on the i3 because of instead of a weave it is forged carbon.
