Still holding onto the audio jack. My last few phones are the HTC 10 (2016), Galaxy S10e (2019) and Xperia 1 V (got it last year). I commute to work daily and my car has an audio jack, CD player, and PC card slot for playing audio. I'm avoiding adapters for multiple reasons - others here mentioning static, and annoyance/inconvenience (want to be able to charge my phone when needed without more dongles). I held off on giving up a physical keyboard and getting a larger phone but eventually gave in on those. Also not giving up the microSD slot.
