"Golf cart that follows you" is a thing.[1] Those have been around for 10 years, and they sell modestly. Suitcases which follow you exist, but haven't caught on.

It might be useful to have a set of suitcases that would follow the user and each other like a train. That would be an amusing option for road cases for rock groups and trade shows.
