Is there any public record anywhere of any auto manufacturer anywhere that is implementing or proposing to implement autonomous driving as a service? Isn't that almost an oxymoron? If your self-driving system requires some centralised service to operate properly, it can hardly be fully autonomous under all conditions. How can it react immediately to an emergency situation if it's not running locally? And if you're not talking about that but just ongoing development work and making updates available after the sale, there's nothing that means that has to be a mandatory service. Either the original version works properly or it doesn't (and in this case, if it doesn't, it shouldn't be allowed on the roads and the regulators should eat the vendors alive). Any subsequent updates that somehow improve the "quality" of the system could be made available at an extra charge, just like new products or new versions of software in a million other contexts, without any need for compulsory ongoing payments where the system stops working if the customer stops paying.
