Dunlop managed to pass on some cycling advice in this ad of theirs from 1966, explaining how to overtake a stationary vehicle safely.
I don't think they were so concerned about dishing out driving instructions in their car tyre ads though because I was once knocked off my bike by a car overtaking me.
The car was towing a caravan but didn't leave enough room as it passed and so when it banged into me, I went flying!!!
