I love having AirPods Pro. Super easy, seems to just work™. Where I have issues with connecting to vehicles. I have a pickup truck that has bluetooth and a 3.5mm jack. The problem is that when I start the truck, it takes about a minute for it to connect to my iPhone. While it's connecting, it's playing FM radio extremely loud. It's gotten to the point now where I just gave up on bluetooth and use a permanent dongle to 3.5mm just so that I don't have to deal with bluetooth.
