UI could do with being updated so that it adapts to a mobile phone browser
Personally not sure how that much data would be "fitted" into a small screen, but I'm no designer
I'm still a little nervous about security though since it's got a token to access the car and it stores all my travel details including my home location so if the site got compromised, it would be a car thief's bonanza.
You can generate a token yourself and use that ... but you have to be a bit of a boff ...
The bloke that created TesalFi is making about $350K p.a.in subs by my calculation ... I don't think nicking cars would be good for his business model You are only at risk whilst the details are in transit to Tesla server. TeslaFi then uses the resulting token, and doesn't retain your logon credentials (and if you change your My Tesla password that will cancel access from all 3rd party APPs like that).
