Not only a passenger Colin , in 1966 with "L" plates proudley displayed I was stopped by the Police , I had 3 mates perched on a board "where the sidecar "should be and my brother on pillion, reason, they were singing there heads off, slightly worse for beer @10-30 pm also my front number plate was on a handlebar fairing so not vertically fixed or as the young copper said not vertical to the perpendicular (?? ) as my brother then pointed out that what he'd said didn't make sense (19 at uni and mouthy ) the police then requested (told me ) to get home or be nicked , no mention of the lads on the board or there apparent lack of safety , slightly different reaction now you'd expect, !! regards and excuse my aside , BobH.
