A crash detection system app that can tie in to the vesc polling data to alert a preset loved one via text or email that a potential crash has occurred.
Make it send last location recorded as well. Pop a notification on the skater’s phone so they know the alert has been sent out too with the ability to follow up with “everything’s fine” or “I need haaaalp!”
I ride in the boonies sometimes and right around 40mph I sometimes think “if I crashed right now, who would even find me?” and that’s scary.
