EOS R6 Mark II vehicle tracking works well

I took these yesterday at a quad bike and sidecar motocross event. EOS R6 Mark II vehicle tracking with spot detection is very good as even with these somewhat unusual shaped vehicles the camera invariably finds the riders helmet and locks on while tracking them - even in the air!
