A few years ago (when I commuted) I was driving in stop start traffic. I basically kept my car moving at tickover in 1st gear while the cars in from would pull about 8 car lengths ahead, stop, I’d creap up on them, then with luck traffic would start again and repeat. A chimp behind me couldn’t hack this and switched lane, passed me out then reentered my lane so they could get ahead of me and join the rest in stop and start routine
