Unless I buy a hybrid or EV…
Unless I buy a hybrid or EV I will disable this feature with third party devices every time. The saving money wise is miniscule. Environmentally you are going to be tossing away 12V batteries faster. Research has shown this. Battery manufacturers admit to working to extend longevity in batteries on stop/start vehicles because they realize this too. A horrible feature the world could have done without. I spent a few years in EV and battery R&D.
