The border crossing calculation uses the VBUS GPS coordinates if available or Android coordinates
if GPS is unavailable. The following instances occur when the driver crosses boundaries between
Canada and US (or vice versa):
a. If GPS coordinates are changed to a different state or province, a remark event is recorded in
the driver log.
b. If the current location is in Canada, the driving rules will automatically switch to Canadian
rules. Similarly, if the location is in the US, the driving rules automatically switch to US rules.
c. If a co-driver is logged in, both the remark and rule changes apply to them, too.
