This is 'just' aggregating the APIs the car manufacturers already expose (for their own apps or 3rd party) - without any additional hardware/direct car integration. So I don't think it's directly comparable.

I tested out the Renault reverse engineered API and BMW Cardata -> each one of them has it's (major) downsides. Especially unfortune for BMW Cardata, which is an official product that had a lot of downtime and really irregular data updates (at least for older cars).

So hats off to the Telematica guys for trying to bridge all this together.
