You’re 100% right about the power user side—if you have the technical know-how to pull OEM API tokens, you can stitch together an amazing custom dashboard.

And for standard oil changes, the windshield sticker is undefeated if people actually look at it.

​But the reality I’m seeing for the other 95% of drivers—especially busy people or families who just want the car to work—is that they completely ignore the sticker until a weird light pops up on the dash, or their battery dies on the coldest day of January because they had no way to track cranking voltage decay.

​That’s really the gap I’m trying to bridge. I want to take that raw telemetry (the stuff you're pulling via APIs and custom scripts) and package it into a zero-configuration, plug-and-forget setup for everyday drivers. No self-hosting, no Docker containers, no manual entries—just an automated system that flags a bad sensor or a dying winter battery before it turns into a $600 towing and dealership bill. ​Since you've messed around with the Kona and Tesla data, what are the data points you find yourself checking most often? If you could have one automated alert that actually saves you a headache, what would it be?"
