It's the maintenance reminder notification on a couple ton metal machine with lots of critical moving parts meant to operate next to pedestrians, cyclists, and other vehicles in public spaces. The maintenance schedule usually is related to safety and good operating of the car over time. Things wear out and should be inspected, serviced, and replaced over time. Should I just be OK with people ignoring the maintenance schedule? Should I be OK with the airline ignoring routine maintenance as well? The transit operator ignoring the maintenance on their trains?
I don't think it's unreasonable to require people to keep to maintenance schedules if they want to operate such machines in public spaces. It's a mistake for these states to relax inspection requirements. I don't mind a notification bugging an owner refusing to do the maintenance on their car. It probably pushed a lot of people to do it who would have otherwise forgotten.
