OK this is interesting news, but what token do they use to enforce the blockchain is cryptographically sound? The article is silent in that regard, and as far as I know, without a token you really cannot secure your blockchain's immutability.
There is no need for a token.
What would a token represent, why would somebody transfer tokens?
It's simple, the block chain is held and maintained by the RTA, instead of transactions is stores vehicle data.
You don't check the balance in an address, you check the the vehicle history.
No real mining, no chance of a 51%, a Sybil or a spam attack.
I thought the benefit of blockchains was that it was immutable and cryptographicaly secured. If it is neither of those two things, why not use a regular database instead?
The only benefit would be a mirrored database and more security since the chain can be hosted in different places and have checkpoints. Instead of back-ups you rely on nodes (probably in this case car dealerships and car services) and they will also be the only ones that can insert info in the chain.
In terms of costs it could be an advantage, since you pass most of them to others.
Besides, just because some thing is being developed it doesn't mean it's actually going to work or it's better than what we have.
Now, asking you a question...
Why would you need a token for this and what would the purpose of trading it?
