Apple music automatically plays in car/headset

Apple music automatically plays right after i get in car. Also same problem when i disconnect a call on my car. this is very annoying and irritating, i did googled and found an option to disable infinity button, i dont even see that infinity button enabled on my phone, this is very irritating and annoying feature, such an expensive item and so stupid features, needs some recommendations from pros or apple community please. it is going beyond my tolerance limits. it last 15 years of iphone usage, i never have to write to community. this is so frustrating...
