I usually pick up the rear but when I lead or ride up front I always signal the number of riders behind. When I cover the last position I use a fist followed by a tap to my helmet, the universal signal for all good, as in all good to hit it hard after me.
When approaching a blind section of a trail I hope that both directions stay to the right side of the trail at least here in the states, who knows what those foreigners do.
When transitioning a dune crest or transitioning bowl to bowl I like to approach the crest and turn right or left to run parallel before committing. This gives me a chance to see other riders dunning on the other side as well I can then see any obstacles. I think this simple driving technique is probably one of the most important ones. There are a lot of people that hit the dunes too hard and even though their bad ass car or bike can take anything and they are the best driver or rider ever, they are putting others at risk with their aggressive driving style. Use the proper technique when approaching anything blind, if you can’t see them they can’t see you.
I know it’s not cool to say but I’m not one to care what others think, sometimes we just need to slow down. After all accelerating is most of the fun, so slow down it’s another chance for you to punch it and feel the acceleration. Drive safe so we all can get more seat time.
