In theory, possibly? But for things like vehicles, and especially land, the existing processes work OK in the places where they are well developed, and where land registries are unclear, NFTs probably don’t help much because the bigger problems are things establishing who exactly is the owner and do you have an effective court system with fair rule of law. An NFT would also have to accurately describe the asset which gets trick with land since it tends to slowly move in places and at the same time old records remain important. Eg in the UK compulsory land registration has been rolling out since the 1920s and the register has existed for nearly 160 years, but title to something like 10% of the UK is not in the land register, and may never be.

No. As has been explored to death in recent articles, the last thing you want is the ability to irreversibly transfer ownership of your car or your home in seconds (and potentially accidentally).

When you have a deed to a car, states have well established laws for how the transfer of ownership occurs, and well established methods for dealing with problems in that transfer. If the deed to your car is tied to an NFT, and than NFT gets fraudulently transferred, it's irreversible absent recourse to the legal system to get a new NFT that represents your deed. And at that point you might as well just have had a normal deed.
