For vehicles like the Tesla Roadster that don't use the modem's GPS, putting the detection only in the modem NMEA code would not help.
Unless the roadster's gps has the same wacky problem with latitude or longitude temporarily jumps to zero (or near zero) and back, I think the roadster should have its own code to deal with gps bugs.

What would qualify as exactly the same bug behavior? If it is specifically that the latitude or longitude is reported as 0, that may not be the same. What we see is a sharp deviation in the GPS position.
So both latitude and longitude temporarily jump? The kind of fix we currently have for the simcom gps (and what I'm proposing we do instead) won't help with that.
Craig, I've forwarded to you separately the data I reported here in 2019. Indeed, the behavior was not that the lattiture or longitude would drop to zero temporarily. Both lat and lon would typically change at the same time, sometimes in opposite directions (signs) and sometimes the same. -- Steve
