Again this inexcusable baloney that testing within 2 hours of driving is some guarantee of safety.
But with Libre, is it with or without apps? Some users might be held up driving by falsely low readings.
And how is " The device was still warming up when I set off driving" or "I was keeping my device/sensor going beyond its use by date or time to save money" going to stand up in court. To me, it just complicates the whole issue of safe driving.
Yes, CGM's with proven reliability and alarms that work based on accurate readings are a boon.
Just not everyone can afford them.
