The key differences is utilities you're paying for the generation & maintenance of key resources - without gas, water and electricity we wouldn't be able to survive. Road tax you're helping to pay for the renewal and upkeep of the road surface (among other local services)... Left alone the road will degrade & will become unusable.
Suspension as a Service is milking what should be a perpetual cost when purchasing the vehicle. If the hardware is already installed, it should be available for the owner to use. They're not paying for the upkeep of the vehicle, or even ensuring the suspension remains functional... All they've done is placed the function behind a pay wall. They can argue they're maintaining the software, but it's utter bullshit and I hate the fact this has become a norm within B2B (for example network appliances)
At least with luxury subscriptions such as Spotify, Netflix, NYT, etc you're getting access to their content, which they renew. Here you get access to something you should have had access to from day 1.
