This may have been true in the past, but when consoles require an internet connection to function, it&#x27;s a small step to turning it into a dead, black box. Even if it provides an offline mode, it will usually require a periodical sync with an online service and this is where you&#x27;re at the whim of Microsoft, GM, Tesla, Sony, Ford, you name it.<p>&gt; I don&#x27;t see any reason you&#x27;d need to have common ownership to implement 3rd party traffic control.<p>You don&#x27;t have to, but once vehicles work in a swarm and do not function stand-alone, you lose the benefits of pretend ownership. I suggested leasing a vehicle and thereby making it clear that you don&#x27;t own it.
