Maintaining the infrastructure needed for all the shite that modern cars are packed with, including the person cost of maintenance is not “pennies”. You don’t just spin up a EC2 instance and call it a day. You need infrastructure across multiple countries, service level agreements, people on-call to handle issues, account management with third-party downstream services, etc.
With that being said, you’ve already paid. You paid for the car, which costs an obscene amount already. If you own the car, you don’t need a separate payment for the software.
