My fear is that safety is so low a priority in the current setup that nothing will change until there is an incident to make people realise how unsafe the race is. Riding it this year was a massive eye-opener for me.
Do the SOS functions rely on mobile signal? The ones I've used (running) all rely on the mobile network. On the Spine Race there is a known signal black spot and the rules ban stopping in this area for more than an hour for safety reasons.
I mean, that's why you have trackers with working SOS functions.
Hopefully TCR can get back to its best.
