Jedibrad,hahaha, what ? Roadtrain ? No idea...
Olivier's technic for Roadtrain is to stop on the downwind side of the road. The wind effect from the road train is not too bad on the kite and its safe cause the kite is over the bush and not over the road.
Also that's why he doesnt have a leash so he can eject himself pretty quickly if something goes wrong.
... maybe warn him road trains are literaly trains on the road!! Oh and warn him about the open speed limits too ie you go as fast as you can, no whimpy 110 kms/hr!!!
Here's some little video's I found on boobtube:
