Just a thought on getting different types of drivers from a 2 b without losing any
From my IAM m/c days
Second man drop-off.
You need;
A point rider/driver. (They must not be overtaken)
A tail- end charlie (they will always be last)
Any number of willing participants.
Everyone gets point and tail end charlie mobile numbers and the route.
Everyone agrees the rules before the off
Point drives near junction for tun off and signals (usually with indicator)
Second car/bike stops and signals and waits for tail end charlie. Point drives off and number 3 follows becoming the second man everyone fololws point and new second.
all drivers pass and take the junction except the tail end charlie who allows the signaller in in front.
at the next junction the second car is directed to stop by point ......
and so on.
Hundred of bikers use this method every week to do social run outs of all lengths and complexities to all manner of places.
Admittedly motorways especially at night are more challenging.
It only ever fails if someone doesn't wait for tail end charlie, the social fallout for not waiting is fairly high
