I followed a blockchain project that initially focused on mobility. They allow car users to unlock and lock their cars, track the location, etc. They also integrate ID management into it. That being said, there's no need for a dedicated blockchain for this afaik, since you just need to timestamp/hash the data and upload it to an existing network with no problem. I won't be surprised if there will be one project that uses the BTC blockchain as its backbone to hash the data. They can also just ditch blockchain and use IPFS, although I'm not sure how reliable it will be if their project is not famous at all. In most cases though, blockchain is just a jargon they use to sell their tokens, while their solution doesn't really need a new/dedicated network/token for that.
