Pretty much everything in a new or recent vehicle is ‘better’ and ‘safer’ until they get worn.
The issue is NOT what you described. The issue is what causes the more serious problems when degradation and failure set in.
You are probably familiar with dead or failing batteries, starters, alternators, water pumps, thermostats, etc.
But do you know what can happen when a sensor, ECM go out?
I don’t think you know. Study up and then come back.
Lastly, note that ECMs and all their sensors may fail long before other subsystems. Lots of cars have a lot of life in them except their electronic control system can fail early and the failure can happen in traffic under very dangerous conditions.
I’ll just note that I recently rented a chainsaw that had electronic control of its carburetor to account for altitude, temperature and air filter plugging.
Once it got a chance (less than a minute) to accommodate to the altitude I was using it at, it ran GREAT!
I think it was a HUSS kah vaaarnaaaah. (insert your favorite Scandinavian joke here)
I don’t think you know. Study up and then come back."
"You should study up."
You have no idea about how many years I was involved in the grimble of what you obviously know nothing about.
You need to give it a rest as you are nearly, totally ignorant.
