Paying with your phone just seems like one of those separation of concerns problem. I'm sure you have backup forms, and cash, etc, but there's something about not having to worry about the multinefarious capabilities of my phone if it's not in my posession.

You could then separate the audio system from your car and drive around with a boombox

Difference is a plastic card that is lighter and smaller than the phone is just as effective as the phone is for payments. When it comes to audio, a car stereo is going to be much more convenient and brtter quality than a boombox or bluetooth. That said, i did know someone with an older car who used a bluetooth speaker instead of their stereo, so they could connect their phone audio.

		I don't know about where you live but here contactless card payments have lower limits than phone-based ones. Also the phone allows me to switch between multiple cards, including transit-specific cards.

Well, that's what we all did like 10-15 years ago with nice double-DIN decks that had nothing to do with the car besides taking power from it and perhaps some steering wheel controls. It was just a hard-wired boombox, 100%. Now, the stereo is in fact properly a part of the Infotainment System you cannot replace, so as it ages out in a perfectly good vehicle, the entire car deprecates faster than it would have in decades past.

Even my 2015 Mazda has enough vehicular settings in the infotainment menu that despite being replaceable with a double-din I haven't bothered because I'd lose all configurability there. I opted for a cheapo $100 carplay unit instead - the modern equivalent of the discman-to-tape adapters ;)

I forget. What are the security implications of having your car play your music again?

Pretty sure Jeep was hacked via their infotainment system and remotely driven (by researcher Charlie Miller)

So it’s actually kind of a real thing

		I'm pretty sure that the infotainment hack was completely orthogonal to whether it was Beethoven, Iron Maiden, or blissful silence. Having said that, a successful car infotainment system attack on android auto or apple carplay could, of course, compromise your phone. So it's up to you whether you decide to cope with that possibility by breaking the law and navigating with a handheld device, or simply declining to do banking on your phone, since successful car exploits mean the attack surface against your phone is much larger than you might presume.
