For my own projects I end up using the WillyWeather APIs as they have a generous free tier and use BOM data - but yeah absolutely echo your complaints, I've seen Google up to 4 degrees off BOM/ my own weather station.
That's why I hate having to deal with touch controls in cars for basic functions. I like having tactile feedback so I can control them without needing to look, or just having a glance instead of having to focus navigating through an interface. Don't get me wrong I love how smarter cars are getting but some things just shouldn't be made "smart" imo.
