i also drive a vw transporter t4 and almost every other t4/t5 driver will wave and on motorways ect they will pull up behind you and follow for miles they have so much respect for each other its unreal.. i pulled over on the motorway a little while ago with a funny engine noise "which turned out to be a fanbelt" and in the time i was stopped 5 other transporter drivers " at differant times" pulled up behind me to lend a hand..
