Why didn't they add a capless gas cap?

Yes. I locked my keys in my car once in 42 years of driving. It was in 1973. I was stoned. Not only did I lock my keys in the car, but I left it running. I popped the hood and pulled the coil wire to kill the engine. Walked about 6 blocks home, got the spare house key I had hidden outside, let myself into my apartment, got my spare car keys and hoofed it back to where my car was parked. After that I always had a spare key attached to my cars somewhere and not one of those worthless metal magnetic boxes. And you know what ? Never locked my keys in the car again and to use a spare key. It's all about training your brain not to do something stupid.
