I love my Olfa Ergonomic rotary cutters. They have a locking button on them. I just put them in my little "sewing case" (cosmetic bag) & off I go. If you're really worried about it, you could put it in a small Tupperware container & keep it on the floor in the backseat, but that's probably overkill. If something happens that causes your rotary blade to automatically extend & fly up and into your body, the cut is probably the least of your injuries. I used to work for an insurance company and heard all kinds of gory tales. Never once did I hear about one of our insureds getting injured by a flying rotary cutter. Close the blade & place it in something (purse, bag, etc) and you should really be fine. I think you have a higher chance of having a swarm of bees fly into your car and kill you than your rotary blade extending and wounding you.
