What specific communication protocols and visibility strategies do experienced group riders employ to mitigate risks and ensure a safe ride when navigating through low-light conditions, especially in areas with minimal street lighting or high traffic volumes? Are there any industry-recognized standards or best practices for group riders to follow when it comes to lighting configurations, reflective gear, and call-outs to alert other riders of potential hazards? How do riders balance the need for visibility with the risk of blinding oncoming traffic or other road users? What role do technologies like GPS tracking, ride-sharing apps, and smart lighting systems play in enhancing group ride safety at night? Are there any specific drills or training exercises that can help group riders develop the skills and instincts necessary to navigate safely in low-light conditions?
