In my non-Telsa, I get decent suggestions with live data built in to the car. I also get suggestions through multiple different apps of my choice through Android Auto.

In a Tesla, you get what Tesla gives you.

I haven't bothered with any accounts in years for third-party chargers. Most just plug in and negotiate payment automatically. Others have credit card readers on them. I haven't personally encountered out of service chargers on my road trips in a few years.

I can charge at most of the major Tesla charging locations as well these days. Ironically, those require I hop on a proprietary app with another account to manage, so I often avoid them.
